If your asset allocation is just large growth stocks and large value stocks, then you are missing out on a whole lot of mid- and small-cap stocks. You did not mention the amount of foreign stocks. It seems like a couple of quick reads are in order:
The Bogleheads' Guide to Investing, Larimore et al.
The Only Guide to a Winning Investment Strategy You Will Ever Need, Larry Swedroe
These books have no fluff and are straight to the point. They also have some proposed asset allocations. Get the books from your library.
