if the baseboards stay on do not cut the doorjambs.

the perimeter grout joint will be broken up at the doorway if you do.

However, if the baseboards are removed, then by all mean cut the jambs and casings.

you can rent a power jamb saw or power undercut saw from most tool rental facilities ... set to appropriate depth for the tile, setting materials, and backer board (if applicable).

you can also use a sharp cross-cut hand saw ... use a piece of the tile, backer board, and a 1/8-1/4" spacer (depending on your trowel notch depth), laid flat on the floor, hten laying your saw down on the tile cut the jambs.

oh and cut far enough back to get the coverage you need ...all the way through the casings is fine as long as the door was properly installed, but I have found on some improperly installed doors that if you cut the whole way through the jamb, it adds a little looseness to the system.
