LT's, Cat back, Lid, P+P'd TB first of all... Good gains to be had there. You can have the stock ECM tuned to fit the modifications done. THen go w/ an LS6 intake if you don't have one already. What year is the car?
Then after the EXH is done, then look into a rear or gears.. Then you can dive into the engine w heads and cam. Depending on what you want the car to do.
What are your HP goals? AutoX? 1/4 mile? Do the suspension also, it'll help you get more out of what you have.

You may get more responses in the 'gen III external engine' section. The stickys at the top in that section have a lot of good info for what you're interested in:
