Definitely get her used to the crate immediately. Make sure she's in it any time you can't be watching her, just like a puppy. Give her treats in it, make it a good place to be, and she'll get used to it quickly. Go slow, let her 'feel you out' and realize that you are a friend. She's been through a lot already and will be confused for a while. She may be on her best behavior for the first couple of weeks.
