You'll be fine with 3.73's in my opinion.

3.73 would probably be fine if you don’t do a lot of highway driving or towing. 4.10 gears would probably do better for your fuel economy.

If you are going to have the rearend rebuilt then yes, 4.10s would be the way to go. If you have 4x4 you need to do the front end too. Will need to be retune for the gears and tires.
