alot of good advice above.
Exercise? How much does she get? A tired dog is a good dog.
Housebreaking? Easy, tether her to you and she isn't out of your site for one second unless she's in a crate. I don't mean to be harsh but, When she has an accident in the house, don't scold her, its not 'her' fault, it's because you are not watching her.
Sign up for an obedience class, you will learn alot and so will your dog.
It's sad to read that you bought her because she was cute and now you may have to rehome her because she is not that cute little puppy anymore and getting into lots of trouble
You may be frustrated, it sounds like she is to, the best thing to do is go to an obedience class with a good instructor that will teach you how to train her, and use up some of that puppy energy in a positive way.
