What is the best way to remove the paint? Can I use a liquid type paint remover and still have the thin set adhere properly?

The best way in my opinion is by mechanical means using razor scrapers, grinders, or sander to scarify the slab until the paint is gone. In the worse cases we use diamond cup wheels.

That said, chemical removers have been used successfully, but please ensure they are properly neutralized or you can have a reaction with future adhesives and additives in the adhesives/mortars that can negatively affect the bond of new surfaces, which is why mechanical processes are the preferred method(s).
