Is there someone you can talk to about changing rooms or something like that if you explain how much of a problem you're having with your roommate?

If not, then I'd talk to her about it. A serious one to one talk because from what you've said, she sounds like a terrible roommate and you need to make her see that some of the things she is doing aren't okay and need to change. You share that room together so you need to be fair to each other with the things that you do or at least clear things with each other before you do them like the turning the lights/tv off or cleaning your side of the room for you.
