Ok, some bullies don't like the sheepskin because they get too hot on it. I would get her a wire crate and let that be her bed/quiet time place. You can put a pad it there for her if you want. Some of mine do not like the pad, so they sleep on the crate pan. As far as the socialization goes, just take it slow as you said she may never have been socialized. You seem to be picking up on the excitement in her and are doing good in making her sit down. When she barks at them tell her "NO"' so she will know it is not acceptable behavior. Just be patient and consistent with her.
