Consistency is key. You can't enforce a rule today and let it slide tomorrow, if you want her to learn. Beware of setting up a situation that can be turned against you. e.g. I would be careful about using treats to lure her off the couch, because a smart dog will soon learn to jump on the couch in order to be lured off by treats. I like clicker training, but it isn't always useful for extinguishing behaviour unless you can set things up to train an incompatible behaviour.
I allow my Basenjis on furniture, but with my first one I was living in my parents' home, and they did not allow it. My girl Val certainly learned to comply when anyone was present, but she would cheat whenever she knew nobody was watching her. She would also misbehave deliberately to entice you to play, or to "pay you back" if you annoyed her. When your dog looks you in the eye, then deliberately jumps onto the forbidden bed, you know the game is on from her point of view! (it's awfully hard to be stern when you are trying not to laugh!)
