I am not sure what is better 4.56 or 4.10 gears with the auto tranny and 33.7 inch tires. If the custom tune is not enough and I change gears after I get the custom tune can I change it in the tuner or do I have to get the custom tune redone?

You will be able to change the gears in the custom options even after you get your tunes.
The only thing about the 4.56 gears is if you do a lot of highway driving unloaded you will be running higher rpms...which in result gives worse gas mileage.
There is a rpm calculator somewhere online that would tell you what rpms you would be running at certain speeds.
