Hi Pebbles and welcome to the forum.
As far as the biting, is this something new and if you pulled your hand back the first time she did it she now knows that she can get your hand out of her cage by biting it.
What you will need to do is just grin and bare it. Once she knows that you are not going to remove your had because she bits it she will quit. You will, at least for the first time, just wait until she lets go. Good luck with that, it can really hurt.
We would love to see pictures.
