What the others said. I'll add that Lowes has Mapei's Aqua Defense, it's a paint on membrane similar to Redgard. You just want to get the membrane thick enough, usually credit card thickness is about right. I usually apply it in two coats to get that thickness.

For thinset, any of the LFT (large format tile) thinsets will work.
