ANY CAR GUYS OR GALS??? I am trying to add horse power to my Trans am!!!!?

Howdy. I am a struggling student who owns a bone stock 1994 Pontiac Firebird Trans Am(6 speed). The car is in great shape, but has 90000 miles. I am looking for ways to increase the horse power. Basically I will have about three thousand dollars to work with for now, but I want the mods I put on now to be the pillar for future mods like a twin turbo kit. I don't know much about cars, but I have thought of headers, cam, full exhaust, a stroker kit, better ecu(computer chip),ddd....I don't think I have enough to add boost(turbo, supercharger) because I would have to pay install and beef up the engine. I am very ify about nitrous for right now too. There is a guy with a 2002 Pontiac Trans Am ls1 and he hits 0-60 in 5 sec flat....I want to smoke him and be able to keep up with the big boys too. I know it is not loads of cash, but if you guys could tell me what ITEMS, the PRICES, and the HORSEPOWER gains that I can expect. Please also inculde estimates for the price of install for the item
