How Long Will This Take?

I thought training a puppy would be easier! My daughter bought the father of this pup when he was 12 weeks old. They have a wood floor in the dining room and it extends into the living room that is carpeted. When he would run across the wood floor to the carpet, they just told him "no, George" and he wouldn't go any farther.
"NO!" is not in our pup's vocabulary!! Neither is 'down, no bite, let go' and numerous others. But she is getting better. She has only made 2 charging trips into the bathroom and jumped into the bathtub, after her last bath. I guess she thinks if I give her a bath she is allowed into the bathroom, NOT!
She has a small red ball filled with polyfill, so it's quite easy for her to grab and carry around in her mouth. She will eventually drop it and let me pick it up and throw it. Then she tears down to the end of the kitchen, grabs the ball, and charges back to my chair. She would always try to jump up on me with her front feet. And I would tell her to get down and sit. After weeks, I have finally gotten her to sit in front of me and I scratch her ears and neck and she finally drops the ball. I pick it up and throw it again. And she does the same thing!
