It's only been a couple of days. Please relax and be patient. Everything is brand new to her and she isn't used to being in a home. To me it doesn't seem so unual that she would have been on the table, which is new to her, or that she jumps at the windows. Do you think it's possible that she knew you were outside?
She needs to be able to bond with you and your wife and to know that she is safe. Do you tense up at all when she is walked? I'm sure she would be able to feel any change in your behaviour, be it verbal or non vebal.
Be patient and give her time and space. See if muzzling her when you both have to leave the house works, and try leaving the radio or the tv on for her since she probably isn't used to quiet.
Good luck! I'm sure it will be fine.
