Put a cowbell on a rope and tie it to the doorknob. Every time you take her out, ring the bell. If she rings the bell herself (in play or by accident) take her out. Before long, she'll ring the bell to go out and you won't have a scratched up door.

If she's wetting the bed, I'd schedule a vet visit pretty quickly. This is the first sign most of us get of a urinary tract infection or diabetes.
