go with the new gear if the budget allows. i think the carriers will have to be swapped for a 3series to 4series jump though. the gears will help you get back the torque your going to lose on the tires.
I used to run 35's with 3.73's in my old K10. It was great offroad, but slow on the street. On a newer truck with OD, I would go with 4.56's instead of 4.10's. Going to 4.10's from 3.73's really isn't that big of a jump. That might get you back to stock revs, but stock is a little low too. The LS1 likes to rev. Plus, you want to compensate for the extra weight and rolling resistance of the 35's. The 4.56's will give you a little extra snap off the line, too.
