I'd take a look around for a Camaro-specific forum. Find one you like with good info and active, pleasant members that nerd out at length and know the cars inside & out.
You'll find out all sorts of tips, tricks, & products to use on your car.
That said, I'd suggest going simple & bolt on for more speed & sound at this point.
The top 2 things I'd be looking for with a 2000 Camaro would be an upgrade to the air intake and a tower strut brace to stiffen the handling but that's just my taste. I have both of those upgraded in my 2010 Challenger R/T & I like it.
Maybe search around on those forums and see what they think of the K&N or Volant CAI system. You could also try just dropping an OE style high flow filter first too. I did a quick search on a major online parts supplier and it turned up a couple CAI boxes and a "Power Tune Kit" which included things like thicker plug wires, nice new spark plugs, a Throttle Body Velocity Stack/Spacer, & a 160º Thermostat. Most of these things are bolt-on & non invasive mods. I'd be wary of the thermostat in MA though as it could end up in a big red R sticker for emissions.
Then crawl under your beast & see what the exhaust situation actually is. If you've already got a nice system, keep it or change the mufflers out to something louder. If you're running stock, look into a Cat-Back exhaust system but keep in mind that'll likely run you at least a grand installed. If you go this route, look into a High Flow Catalytic Converter & Headers while you're at it. While I'm on Headers, those you could probably do for around or under $500 _IF_ you install them yourself, which, if you're inexperienced, will be a _very_ frustrating learning experience. You're also gonna want to try & make sure whatever system you get will mate up to your existing gear or the gear you're installing with it.
Do all or some of this stuff & you've done a bunch to get more out of what you've got AND free'd up your intake & exhaust to take on future mods. This is all stuff you'd need to do along with things like cam swaps, lifters, roller rockers & boosting.
What I'd suggest you get (FIRST!) if you don't already have, is some of those Mechanix style gloves & some thick leather/hide gloves (you will tear your hands up plenty), some decent & comfortable shop goggles (you will get rust & debris in your eyes), a flannel/cotton long sleeve work shirt (poly doesn't get along with heat) * some good respirator masks. Then get some basic, good quality tools. This will help keep the fun in your project by filtering out some of the pains.
