TBapp,
I just did gears about 2-3 months ago in my car and went with 3.73's since I was supercharged. AWESOME choice..!
I had about 70,000 miles on my car when I did the gears so here is what I bought:
FRPP 3.73 Gears

Traction-LOK Rebuild Kit

Full Install bearing Kit

You may also want to get a differential cover to help with keeping the load on everything - it will help when you supercharged...
It's a huge difference though and the car drives really different with the gears including once the traction-lok system was re-built... It's amazing..
Good Luck to you and Get that car supercharged soon!!
