Congratulations on the new ride. It should be a lot of fun for you. I don't envy your insurance bill, but if y'all have it to spend, I'm not going to hate.
Well the V6 comes with a 3.27 final drive. The V8 comes with 3:54 gears. I'm guessing they are interchangeable. That would certainly make you quicker.
Even the V6 camaro is a heavy beastie...so make it lighter. Back seats are for suckers. I know yours don't fold down, so I'm not sure if they are even removable. You could remove other bits too, but I'm guessing you are partial to your sound deadening. They already make cf hoods for the car, and that could save you a couple pounds. Somebody already said light wheels, do that.
Most aftermarket exhaust systems are lighter as well as better breathing, which helps on both fronts. You could get some lighter front seats too, if you aren't totally sold on all that airbag malarky.
They make uprated trailing arms, which I'm guessing might be lighter, and they will help you launch=faster. There are some things you can do to make the transmission shift a little more aggressively which would help, but I'm guessing they aren't warranty friendly.
Above all, learn how to drive. I don't care how good you think you are, you're 17...which means that you haven't been driving long enough to know shit. Go autocrossing or something. It's fun and you'll learn more in a day than you would in a year on the roads.
