ceegee - Standard is to put your money in a Roth IRA when you are young. A roth is like a traditional IRA, but instead of getting taxed when your old. It gets taxed now. So assuming you are in a high tax bracket later on in life this will be smart. An IRA is suppose to yield on average 8%/year on average (2% one year. 14% the next).
The math comes to you'll pretty much be a millionare by retirement if you invest 4k/year. 100/month is better than nothin'. Hardest thing to do is start. Once you get in the swing of things it's kinda addicting looking at how much money you save and how much it grew. Hopefully you'll be inspired and/or have the option to put more in. Vanguard is good. E-trade is good. Just google 'Roth IRA Options' and you'll find a place you like.
