There is not just the problem of returning the overall rear gear ratio close to stock. You also have to factor in the added weight of the oversize tires and wheels and the increased rolling resistance. It takes more torque to get and keep them rolling. While 4.10:1 gears seem ideal the 4.56:1 will add the lost torque.

I suggest 4.56 too. Currently I'm getting between 13.5-14 mpg in the city. Best mod I ever did, performance wise. 3.73 won't be worth your time or money and 4.10s won't do a whole lot either. I'm also not sure if they make the 4.10's for our front ends. Definitely go with the 4.56's. I went to 4wheelparts and it cost me $1400 installed with master install kit. So yeah, your price seems in the right ballpark.

$1600 is about average. About $600 for both front and rear gears then all labor. They have to be installed PERFECTLY or it can mess up the gears real quickly.
Going from 3.55 stock with 35" tires and regearing to 4.56 is about 3.77 but with all the added weight in tire and the lift, it's about perfect.
