+2 on reading the Collins stock series linked in matchewed's post. Or buy Collins' book if you prefer a book format. ;)
My opinion: You're over complicating things. You don't need 5 different funds as you're basically overlapping in several since things like the 500 fund are also in the total market fund and probably much in the growth funds are also held in the others, etc... and splitting up a 30K investment into little chunks like that isn't necessary and not very efficient and you're paying a bit more in fees than just going all in on VTSAX.
Read up on investing at that link, figure out your asset allocation first, and then find a couple (2 or 3) funds that fit. Like a total stock market (VTSAX), a total international (if you really think that's necessary; as most of the total U.S. stock market does business worldwide, it is posited that adding international isn't necessary), and a total bond fund if you think you need a little smoothing for the bumpy ride.
The five funds you've listed are all stock index funds, so you're talking as volatile (risky) as it comes at 100% stock asset class. You mention going "a little aggressive" but this is 100% stocks so there is no "little" about it; and it will be as volatile as it can be without any bonds or other conservative funds. Not that I think a 100% stock portfolio is bad, but I'd have to ask are you prepared to weather the crazy roller coaster ride?
But if that was the case, I'd just go all in on VTSAX and be done with it.
