Have you thought of fostering or bringing in a second cat? You'll see an almost immediate improvement in her biting and scratching if she had another cat around to "teach" her cat-ettiquette. I had a foster that did exactly what you described, and I knew it was just play to her, nothing agressive (I'm going to assume your kitty's doing this out of play too). She came to me as a foster because nobody wanted a cat that did this. She was adopted and returned several times in her short life. Then she came to me.... and my moster crew took care of her within a few days.

Every time she tried to bite me, I also said a stern "no bite" and blew softly into her face. She hated that and connected the negative face blowing with her actions.

PS: Depending on how young she is, it MIGHT save your sanity and hers to adopt another kitten! Kittens have more energy than they know what to do with and two entertain each other and offer unlimited social benefits.
