Congrats on getting the 401K, and bravo on contributing! I agree w/ BA that putting everything in the Freedom fund would be a decent way to start. Here's how the Morningstar X-Ray broke it down...looks pretty good:
Portfolio
Cash 3.72
U.S. Stocks 63.09
Foreign Stocks 18.50
Bonds 10.30
Other 4.41
Not Classified 0.00
Can't copy over the stock style diversification, but it looked pretty well spread out.
I noticed the X-Ray showed all of the bonds as low-quality ... that would bother me, but I'm much older than you and quite conservative ... it may not bother you.
If you want to toy with some other scenarios on the X-Ray, here's the site:
