Green drywall is fine for the rest of the room. Be sure to let things dry out well before sealing it up again.
We use DensShield as a tile backer for most applications. It's lighter than other backers, cuts and installs much the way drywall does, and has a built-in vapor-barrier. We glue and screw it with galvanized or ss screws.
