When I rebuilt my turbo I used the Garrett rebuild kit with the 270 degree bearing and the Riffraff billet wheel. Runs great and cured my surge.
As for special tools you will need to have a 1/4" drive 12-point 8mm socket otherwise you will not be able to remove the backing plate bolts. I also had a small Tupperware container with a pool of fresh oil to soak parts in before install. The rest is pretty straight forward. If you want to see what it entails here are good write-ups depending on which kit you go with:
