Albert Gonzalez is calling it quits. Accused of masterminding the largest identity theft in the United States ever, he has agreed to plead guilty in U.S. District Court in Massachusetts. Separate charges filed in New Jersey, however, remain.

The 28 year-old faces 15 to 25 years in prison and will forfeit $1.65 million and a Miami condo (in addition to $1.1 million already seized). If the judge accepts the terms, this would be the longest sentence ever recorded for a hacking case.

Staples (NASDAQ: SPLS), a seller of office supplies and a competitor of chains such as Office Depot (NYSE: ODP), OfficeMax (NYSE: OMX), and Wal-Mart (NYSE: WMT), reported Q2 earnings on Tuesday. Although they weren't that great, I can't say I felt they were a total disaster, either. I think the quarter was lackluster and indicative of the immense work ahead for management in terms of getting people into their stores and increasing sales per transaction.

According to the press release, total sales increased 9% and adjusted earnings per share declined 24% to 16 cents. That's a steep drop, but they did match analyst expectations. Staples used the increase it saw in free cash flow in a smart way: debt reduction. I approve of that move, to be sure.

As the current advertising campaign from Staples Inc. (NASDAQ: SPLS) makes clear, the nation's largest office supply store operator is hoping for what so many retailers (aside perhaps from those participating in the cash for clunkers program) are hoping for: a boost from back-to-school sales. Unfortunately, any such sales won't affect the second quarter results that Staples is scheduled to report tomorrow morning before the market opens. Those results will include July, though, when retail sales were disappointing all around.

Staples is scheduled to discuss its second quarter 2009 results tomorrow morning in a conference call at 8:00 AM ET. You can catch the live webcast of the call on the company's website.

With the recession still in full swing these days, retailers continue to try and entice consumers into stores with discounts, special programs and new and improved gimmicks to ensure sales don't decline to drastically. So, in that sense, does it sound logical that some retailers are actually opening new stores? In some ways this may actually make sense, as long as you still to small, efficient and highly profitable.

OfficeMax, Inc. (NYSE: OMX), Best Buy, Inc. (NYSE: BBY) and others are opening concept stores with a very limited selection of items in some markets and areas where full-size stores would be a huge risk. Best Buy has it Best Buy Mobile concept stores filled with high-margin wireless accessories and commissioned wireless handset and contract sales, and OfficeMax is launching stores with a selection of extremely popular items in stores as small as 2,000 square feet.

Staples (NASDAQ: SPLS), whose colleagues include Office Depot (NYSE: ODP) and OfficeMax (NYSE: OMX), is set to report earnings for the fourth quarter on Wednesday, March 11. The famous seller of office supplies has seen its stock go from a 52-week high of $26.57 all the way down to a 52-week low of $13.57.

Actually, that's one of the better ranges I've seen! Goes to show how bad things are out there. Staples saw its shares close at $14.63 on Monday, so a beat on the bottom line could really help things out.

Will management be able to beat? I don't have much confidence that it will, but that doesn't necessarily have to do with Staples per se, it's just that the economy's got me down on so many of these earnings prospects. Analysts are hoping for Staples to do about 42 cents per share in Q4, which would represent a 10% drop in the bottom line.

Among all the negative economic data that came out last week was a positive surprise: retail sales were higher in January. A fluke or a glimmer at the end of the tunnel? That may depend on whether we see any positive surprises arising from items on this week's economic calendar:

TheStreet.com's Jim Cramer says companies saddled with high debt loads can be found in every sector in every business.

Overleveraged. Too much debt. Need to pay down debt. How many times have you read that story?

You read it so much because it plays out every day and plays havoc with stock picking almost every time you see a savory stock down on its luck.

This weekend, as I went through the charts, I was amazed at how low some stocks have gone, stocks that I would normally say to just take a flyer on, but turn out to have so much debt, short- and long-term, that they are just too dangerous.

Consider these perhaps poisonous morsels:

Analyst downgrades:

Poor Office Depot (NYSE: ODP). Have you checked the price of the retailer's stock lately? It closed on Wednesday with a value of $2.10. It actually rose over 11% that day upon news of its third-quarter earnings. I can assure you that I wasn't buying the stock.

The numbers didn't tell the story of a company that would make a worthy addition to a stock portfolio hell bent on hanging tough during a market meltdown. Instead, the 7% revenue decrease and the loss per share, on an adjusted basis, of $0.01 relate a tale of a business that one should ignore. At least that's the way I see things. Comps in the North American retail division were horrible. The return on invested capital as calculated by management took a significant drop. Let's face it, Office Depot just isn't cutting it. Granted, the economy is wreaking havoc on the business, but come to think of it, I don't really have a good picture of what the brand is supposed to be about. Well, I know it's about office supplies, but why should I shop there as opposed to Staples (NASDAQ: SPLS) or OfficeMax (NYSE: OMX)? Good question, huh? Looks like the retailer needs to get the message out as to why the shopping experience at its locations is of a higher value compared to the office stores mentioned. For that matter, I'm sure a lot of people use Wal-Mart (NYSE: WMT) to pick up office supplies too. My point is that management needs to step up its game and create some better marketing programs for its stores. Be creative like Staples. That "easy button" device is turning into a cool cultural icon (well, I might be exaggerating, but I think it's creative, at any rate).

Earlier, I said "at least that's the way I see things" in terms of my opinion about the sad state of Office Depot, but I suppose I should point out that there are obviously a lot of investors out there who don't see a lot to love when it comes to this chain. The stock is down over 63% on the one-month period at the time of this writing. I see no reason to speculate on this business. The economy isn't getting better, and Office Depot just doesn't seem to be in a strong position. What will it take to turn things around? Like I say, in addition to hoping for an improved macro climate, come up with a better advertising campaign, build a more intense connection with the consumer. Office supplies are commodities, but shopping experience is not. That's the opportunity. Differentiating a brand from the competition based on things like customer service and an easy time of it at the checkout register is a traditional strategy in the retail industry. If Office Depot can offer something in that area, it should let me know about it. Since just about every retailer is struggling to keep the traffic coming into their chains, now is the time to exploit the other guy's weakened state and grab every customer possible.

Disclosure: I don't own any company mentioned; positions can change at any time.
