I got it done, so far, so good. I was able to remove and replace the screen without removing anything but the back cover -- I just loosened the long plastic bracket by taking out the 3 screws near the bottom of the phone. This was enough to undo the old ribbon cable connector and pull it out then feed the new one through and snapping it down. Phew -- I was dreading trying to put everything back where it belonged if I disassembled the whole thing. No thanks to the crappy Phillips screwdriver included with the replacement screen.
