1) yes
2) yes
3) i'd start with the bolt ons as they are the best bang for the buck. 100 or so total for an ebay cai, 200 for an underdrive pulley and belt, and a few more hundred for gt take offs or otherwise aftermarket catback. after you're done with those, gears are definitely the next step. once you have them along with a tlok, you'll never wnat to go back, trust me. driving slowly around town you won't notice it as much, but as soon as you floor it, the rpms will climb a lot faster and you'll be glad you got them.
