Leave her be until she's fed again and just feed in her cage. No real reason to move to a separate container, will just stress the snake out further.
Give her a couple days after that before handling and don't take no for an answer if she hisses. She's associating you/humans in general with a fall and she's trying to get you to go away. If you keep leaving her alone it will only reinforce that the hissing works and encourage that behavior.
