Leveling a floor, Best way
update: I realize what you are saying. That the idea for ceramic tile is to make a floating floor to allow plywood expansion. but without that space between wall and plywood (which would be filled with a leveller), you no longer have a floating floor.

As for the asbestos tiles, the general rule is that unless you sand, etc., asbestos should not be a problem. Asbestos is a danger as a dust. Sanding or grinding the tiles would create dust as would (very slowly) wearing the tiles out by walking,etc. on them. With the asbestos glued into the tile, you can pry the tiles up.
