hello there and welcome.
Sounds good, i know ur going to enjoy the pony.
For mods, you can replace the throttle body, Intake Plenum and Manifold. You can also change the pulleys. more or less 850-1000. in expense, depending the brands. if you buy a packeage all together its cheaper. get an X-pipe(catless) with either flowmaster 40, or magnaflow depending on the sound of you like. Then into the future you can throw in gears and new chip for the ECU and last but not least SUPERCHARGE IT!
hope everything works out well...
