The chalk paint should stick just fine on the top- I am sure some of the things I have painted were previously waxed. I always clean off the furniture with blue windex- spray a little on a cloth- gets all of the dirt off. the furniture from a thrift shop can sometimes be a bit dirty. I also use the windex as a tack cloth after sanding( trick learned from my DH's woodshop teacher Dad -cheap, non toxic and alcohol based so it doesnt affect the wood.
The Johnsons only comes in the one color. I seal the chalk paint with that and then distress and then sometimes use the AS dark wax. Please post pics!

I recently found out about a similar chalk paint, but less expensive than Annie Sloan's. ;o)

Thanks CB! I looked at the Johnson's wax today. Great info re the windex!!

Patty - I've already bought the ASCP. If it goes as far as I've heard, I don't think it's a bad price. I was able to see pieces painted with it and loved the finish. Thanks for the info!

Tina that is correct- I can get an incredible number of pieces out of a quart of ASCP - without thinning- so it is cost effective. And I like to use two coats of paint in my work.This paint is a dream to use and distress!
Did I mention I use the Johnsons even on Old White paint, but IDK about on the pure white.
Glad to help- let me know if you have more questions.
