The air registers come through the floor. That shouldn't be a problem, except the aluminum flashing is tacked onto the top of the subfloor. Basically, I have a 1/8" tall lip extending an inch around the air vent opening. How should I handle that?
The fireplace in the room has a nice piece of slate, 6' by 3' by 3/4" thick, glued directly to the subfloor. No chance it's coming up. I don't want to destroy it. Should I tile up to it and incorporate some type of transition?
Thanks again for the help so far. You guys have kept me from making mistakes that would have destroyed the project by now.

Issue 1) Registers: Ignore the flange fastened to the subfloor. Lay the backer board over the metal. The registers should have a flange that is long enough to fit inside the new tile and backer board. You may want to fasten this directly to the finish floor with concrete screws, plastic fasteners, or my choice, construction adhesive.
Issue 2) Slate Hearth. I agree, dont mess with the slate. Get some marble thresholds from your supplier (HD or Lowes have them). Set these directly on the subfloor and but the backer board and tile up to them. This will minimize the elevation change to the slate. You will have a depression left at the hearth that will show great ability to catch dirt, but I think this would be the least worst choice.
Another issue is the one I find the biggest pain, cutting around door jambs to slide the tile under. Use a flat saw and cut enough away to hide the edge. A Japan Saw works best.
Good Luck,
