I think you should go with the 4.11 gears rather than the 4.56 gears. I have the 4.56 gears in my trail-dedicated CJ7. Even with 35" tires, the gearing is too low for me to travel any considerable distance on the highway -- rpms are just too high at 60-65 mph. Yours would be even worse with 33" tires, especially since you say that it's a daily driver.

You could probably get away with 3.73 gears, but I think you'd be happier with the 4.11 geaars once you get off of the pavement.

Personally, I would never drive a 4x4 that had different gear ratios in the front and rar axles. That's a MAJOR screw-up just waiting to happen!
