I just recently did some research and got the book "The Skin Type Solution" by Leslie Baumann, MD. and she actually recommends avoiding jojoba oil if you have oily acne-prone skin.
I second the glycolic acid. I just started using the Neutrogena Oil-Free Acne Wash Daily Scrub which contains beta hydroxy acids (2% salicylic acid) and alpha hydroxy acids (glycolic acid). So far I like the product - I only use it in the morning and then I use the Purpose Gentle Cleansing Bar at night before I apply my 2.5% benzoyl peroxide lotion.
Here are the ingredients for the Daily Scrub:
