I have had the same problem with extremely oily, acne-prone skin my entire life.
I use pure jojoba oil mixed with aloe vera gel. Just use 2 drops of the jojoba oil mixed in your palm with a dollop of aloe vera gel and rub into your face and neck. Morning and night. Thoroughly Clean Facial Wash by Desert Essence is a great mild cleanser. Spot treat any acne simply with drops of pure tea tree oil. If you must use a toner, try witch hazel (I don't use a toner). Jojoba oil is very similiar to the sebum in your skin. It "tricks" your skin into thinking it has produced enough oil, so therefore your skin does not bump up the oil production. The jojoba oil will feel slightly greasy at first, but after a few minutes, your skin will thoroughly absorb it.
I do like the whole idea of mineral makeup, however, I was not impressed with Bare Escentuals either. Try L'Oreal's line of mineral make-up. It has great coverage and lasts longer.
This regime has worked very well for me. My skin is so much clearer, it's not as greasy, and I get compliments on my skin's "glow" all the time.
Good luck!
