first of all welcome to the site dude.
Now for the boltons ill give you a quick insight.
You want to run 11.9x or so. Pulley, intake, tune, exhaust and 26" drag radial. Will make 450-470rwhp depending what pulley you use. If you install a set of 4.10s you will run 11.6 if you got some decent driving skills. Leave the clutch alone. It will be fine. As far as what parts to use. If it was me, i would put a jlt cold air or ram air intake or a k&n fipk , get the regular magnaflow 2.5 catback, not the magnapacks, bassani hi flow catted 2.5" x pipe. As far as the tune goes, go see shaun at aed. Now for the pulley i would run a billetflow upper pulley. Get a 2.76. For the tires run a hoosier drag radial for best times at the track on a radial. Street longevity wise their not the longest lasting. Ngk tr6 plugs gapped at .032 and a heat exchanger upgrade wouldnt hurt. Proper belt length will need to be found. Use gates. Get the idlers pulley if you can, they will help.
