Nitpick, growing into a point:
Zero-interest loans (including, in the very short term, credit cards) are free money. For example, I got my Lasik at 18-months-no-interest financing. I could easily have paid cash up front, but instead, I’ll make the minimum payments for sixteen or seventeen of those months, collecting interest all the while, and then pay off the balance at the last opportunity to do it before interest kicks in. End effect: I get about $200 in interest that I wouldn’t have beforehand. I could play a little hardball and probably make it $300 or even $400 if I got lucky (with the caveat that it could be $100 if I were unlucky or I could come out behind if I were stupid). Even if something happened to my financial situation, I could blow away the loan at any time without repurcussions. Free money.

If you start thinking about money as a tool, as leverage and potential, then your finances become this mercenary game, and… hey, free money.

Your first point has one pitfall that I’ve seen people get into…the fine print. At the end of those periods, some 0 interest financing will have a stipulation that if you owe even $1 on the account, you can be charged the interest on the WHOLE amount for the ENTIRE period. So, yes, great idea for those of us who are fairly certain that we will always have enough money to make that final payment in 18 months, but for those living hand-to-mouth, who knows how much cash they will have? And then they can get spanked…So yes, great idea if you play the game right.
Your second point reminds me of something that I’ve heard: “Those who understand interest, earn it. Those who do not understand interest, pay it.”
The most important thing for most people living on a tight budget is to get rid of their credit card debt ASAP. If you have more than one month’s (half a month?) income of credit card debt, then don’t worry about other investments. In a simple way, the interest you pay on credit cards (I think the highest card I had once was 21%) is more than the increase in most stocks will make…
Also, Sharebuilder was an easy way to get into index funds, I think the iShares are the ones from Vanguard and are pretty good. 50% in the S&P500, 15% to 20% Nasdaq, 15% to 20% Russell 3000 and 10% each in Europe or Asia will give you a diversified portfolio that you can pretty much invest in and forget about.
