I root the fun way. Dl the files in the unlocking guide here in the sticky for roms. Once unlocked and rooted. Check out my thread for tiamat and enjoy
The check update still does nothing? In the same area you found the root look at locking and getting back to stock posted by Phil. Dl the stock files they are 3.0.1. Do that and once on 3.0.1 try the check for updates. I went to 3.0.1 last week and soon as it booted it took me to 3.1. Then when that was done it went right to 3.2.

fixed! kept flashing ROMs from the MotoDev site until I found the "right" one - I must have some bastardized version of the XOOM - anyway, after I flashed, I automatically received 4 updates - Now on 3.2.1.
Now, if I root this, will I continue to get updates?
