Ok, so I narrowed it down to Power Wires and 4.10 gears. I know that there is an exhaust out there that will help it too, but which one? Will air intake help? Someone told me it will. Any would would be greatly appreciated!

There's one thread with links to articles all over the net, it's great.

The jist of it all is that per engine size, improving airflow in and out of your engine and optimizing spark will only do so much and that what accounts for the biggest factor on gas consumption above 55 mph is aerodynamics, and below 55mph is rolling resistance (weight of vehicle, tire pressure, bearings, etc...). However if you are aiming at improving airflow you focus should be on headers first.
