The 2.73's will be just fine. Your talking a street car and not something you will be at the track competing with other cars to win every weekend.
The gears you have will be just fine.
What is nice about this ratio is it will hold 1st. gear longer and complement the torque of the supercharger.
Put the supercharger on first and if you decide you want a lower ratio, It can be done later.
Your automatic has 6 gears and nicely spaced apart,
Spend your $$$$ on a Axle Exchange aluminum drive shaft.
