The fee's are the same as the rest of your CCBill account for adult products. If you have non adult products, we can do the same setup through our mainstream payment system at 4.9% plus $1 per transaction there.
As far as sales tax - your cart software will be posting in the price to charge on the CCBill form, so that's done on your end before getting to CCBill.
