I like Burt's Bees exfoliating soaps (peppermint or citrus spice). While they're not specifically labeled for clearing up acne, or even as a facial soap, per se, I have found they are really working well on my skin. They are exfoliating soaps though, kind of abrasive, so they may not be for everyone.
Anything with salicylic acid in it works great! Oh, and sulfur.

I had a face cleaner at one time with sulfur (can't remember which kind, it has since been discontinued) that did an awesome job. It's very hard to find anything that has the sulfur or a derivation of it....you have to look at the ingredients. I don't think it's recognized really as one of the better acne fighting ingredients, but it sure helped me out.
I have never thought that benzoyl peroxide worked for me, just dried out my skin.
