This would be a good question for Robi.  I'd roll it into another 401k, preferably the one with the next company or organization you're working for. 

I am not sure which type of plan has the best tax options 401K, IRA, Roth IRA. But when you get to picking the actual fund choose either an S&P 500 or S&P 1000 fund. There has never been a 20 year period over which the broad market has failed to get a 7% return (and yes that is adjusted for inflation). So go with that it is safe and out-preforms almost all the other funds over the long haul. The fees are usually very low on this type because computers do it all, and you are not betting that the fund manager has some hot tip or anything.

If you want to try your hand at the Stock Market, I recommend http://www.betterinvesting.org and http://www.motleyfool.com. The returns from carefully picking stocks is far superior to almost anything else. At your age you have a lot of time for your portfolio to grow.

Well Ryan, I don't know an incredible amount about the subject, but if it were me, I'd roll over into your new employer's 401K plan rather than a Roth.  A Roth is a great product, but your employer will probably match your contributions to your 401K which means you'll make more, and since you'll be with a college, my guess is taht that the program there is pretty good.  I guess another consideration (one that you probably already realize but I'll keep going anyway) is that it'll be pre-tax dollars going into the 401K, so when you're 59 and 1/2 you'll be in a better tax bracket and probably pay less taxes than you would on the money you made to put in your Roth IRA.  I could be telling you wrong information and I know nothing about the stock market.  But when you're a little older I can sell you an annuity.
