Do I need a torque wrench for GMC C/K 3500 wheels?

Yes. An impact gun over-tightens unevenly, which can warp rotors and stretch studs. Snug the nuts in a star pattern, then finish each one with a torque wrench set to the value above.

Should I re-torque the lug nuts after driving?

Yes. Re-check after the first 50 to 100 miles. The wheel seats against the hub as it heats and cools, and nuts that were correct in the driveway can read low a week later.
