investopedia.com and fool.com are two great sites to get you started.
In my opinion, with something like 6k to start with stocks are your best bet. I know you mentioned you wanted to avoid them, but your alternatives are pretty pedestrian in comparison (ie: gov bond earning you a whopping 2.4%). You could look into things like microloans but these also carry inherent risks.
If I had 6 grand and was just starting out, I might look at…
1.) Gold and/or gold mining stocks. In my opinion, its a pretty safe bet that gold is going to keep going up for some time to come. Some conservative estimates indicate 1500$, other guys like Peter Schiff are leaning towards 5 grand. I’m sure you’ve seen all the “we buy your unwanted gold” ads popping up everywhere…a lot of people are banking on the hypothesis that gold will shoot up.
2.) CANROY (Canadian Royalty Trusts). Many of these are related to natural gas and oil exploration. They pay great dividends (8%-15%). Some are targets for foreign buyouts…one of my holdings (HTE) just made me a mint when it got bought out by the Koreans. Keep in mind that these dividends will only last until December of 2011, when the Canadian government changes the laws about CANROYS. Enjoy it while it lasts.
3.) Natural Gas. This is a long term investment. Right now the prices are getting beaten into the ground, but its only a matter of time before the US starts relying heavily on nat. gas.
4.) Beaten down Blue Chips: Awesome companies that are at very low points. My favorite is Alcoa (AA)…if you think the US will ever need aluminum again you might want to look at this one.
I’m not a pro at this, just an average investor who has done a decent amount of homework. The key to investing is to study stuff yourself and make your own conclusions.
