http://www.gmtuners.com to get a basic tune done on your PCM after completing the physical part of the swap, to get the car going, then you'll need to have it tuned properly at a dyno tuning shop.
Also for motor and trans mounts Fierorog makes some very nice options and you can contact him on Facebook, he has other swap parts as well:

Good luck with your swap~
