The mounting (humping) issue may be just play, or a dominance issue. Mostly its just males that go through it but as you have seen first hand sometimes females. Nothing to be concerned over unless it continues. Then if it does I would seek my vets opinion.
As far as the happy peeing, it might not be "happy" as you think. It might be submissive peeing, which means she is showing you she is submissive. I would try to ignore her when you first come home, go about business with out making a fuss over her. Does she roll over on her back when she does this?
