What stocks should I invest the rest of my money in?

In consumer economics, we are playing a game with virtual money that we invest into stocks. The results are based of how well the stocks do in real life. At the beginning of the game we were each given 1 million dollars. So far, I have invested $679604.50 in the following companies; AFTBX AMZN ASTM BAC CAT CEE CSCD CSCO DPS EPIC FGNRX FLWS GE GEN GLFIX JPM KKR LB MSFT MSSR NYX OFSI OREX PFE PRD SRX UNTK VVUS XING. Right now, I am in DEBT of $5,867.28. Does anyone have any suggestions on how to the rest of my $320,395.50 and get rid of my debt? The more spread out, the better.
