Torque specs on bolts that hold Carrier in rear end?

You are talking about the two bolts that attach the main caps, right? If so, it's 70-85 ft-lbs. Remember to make sure the caps are on the correct side, and the arrows point the same way as they did when you took them out.

The link at the very bottom of my sig has a link to a gear install write-ups and some tidbits from me. Should help you out if you need it, but sounds like you are already close to being done.
