I recently opened up my 401k. I will admit, that I did not do much research in choosing my investment option distribution. 
    
Does anyone know of a good book (or other resource) to guide me in my 401k choices?
I am not asking to be spoon fed, but honestly I am not sure where to start.

EDIT: I am only a year out of college, so I am sure I want to be pretty aggressive.

For reference, see below.

Currently, I am investing in.
I chose them basically based on past returns that are listed.

    Stock Investments 	LARGE GROWTH 	XXX S&P MGD AGGR GTH 	10%
    Stock Investments 	-- 	XXX MELLON SP MDCP B 	10%
    Stock Investments 	MID VALUE 	XXX/GS MID CAP VAL B 	10%
    Stock Investments 	SMALL VALUE 	ABF SM CAP VAL INV 	10%
    Stock Investments 	SMALL GROWTH 	WFA SM CAP OPPTY ADM 	10%
    Stock Investments 	-- 	XXX TRP ESTAB GRTH B 	10%
    Stock Investments 	-- 	XXX TROWE MDCP GTH B 	40%

These are my available funds.
