How long do I need to lurk after installing the backerboard before I can lay the tile?
Can you apply caulking over caulking?
Answers:    Screw the backerboard to the studs, cartridge the seams beside mesh tape and cover the cartridge with thinset. once this dries (a few hours) you are organized for tile. Good luck!
Foundation walls?
Make sure when your installing the backer board that near are no gaps between the sponsor board joints, huge gaps will allow moister to take behide the tile from inside the wall's and the tile will fail after time you can use trim set to fill any you might enjoy.
