The purpose of a TR fund is to allocate your portfolio for you. Having money somewhere else means you're allocating money, yourself. At 90% equities, your TR fund is probably already heavily balanced toward the S&P 500. Putting 50% of your contributuions into an S&P 500 index fund means you're probably heavily overweighted in that direction. I have an aggressive portfolio allocation myself that's 50% in an S&P 500 index.
I try not to offer unsolicited advice because it can seem condescending (especially in text-only mediums) and is worth what you say it is, but I suggest doing some reading on portfolio allocation/balance. I can't give you anything very specific because my allocation is a basic 50% large-cap, 20% small-cap, 25% foreign, and 5% cash.
That said, congrats on starting your retirement planning so early. Compound returns are a very powerful force in investing so the sooner you start, the better. 
Congrats! I'm not sure your age, but it's good that you're starting young. I'm 27 and JUST opened up mine as well. I agree...it does feel good
congratulations. I wish i had invested in to Roth IRA's sooner. I'm at the point in life where I no longer qualify because of income restrictions.
