Cement Board / Drywall Joint
I'm working on finishing a bathroom, and I have two joints (one of them a 90 degree outside corner) where cement board (durock) bumps up against drywall. When I fill these joints, should I be using fiberglass mesh and thinset like I would between the cement board joints, or should I be taping and mudding them?

Use durabond to fill the joint. If your tile will be coming very close to or right up to the corner, I'd suggest you use a vinyl cornerbead there. Coat the cornerbead with durabond, then finish it with lightweight setting compound (easy sand).
The fiberglass tape you use on cement board should work fine.
