Are you an auto? Or a 6-speed? If you are an auto, I would stick with the stock gears, and just go for a torque converter and a shift kit. If you are a 6-speed, I would put in gears. Even with 4.10's in a 6-speed, 6th gear at highway speeds won't be much in the RPM band. It might even improve mileage.

The basics to help mileage and increase power though will be the exhaust, and a CAI, along with a tune.
