As far as gears go, 3:73's for an auto at best if driven on the street. Depending on how much boost you go with you may want to consider 3:55's instead. As far as size of injectors, how much boost are you anticipating? With 8-10 lbs I'd use no less than 36lbers , 12-14 lbs of boost, step up to the 42lb injectors, and then you can ditch the fmu too.
