With regard to your wife leaving the nails up, my wife did the same thing. In fact, she just took her stuff and left any mess that was remaining. The first move out day (it took her two days), the house was a mess, but I was able to clean a lot of it up. The second move out day was a lot worse and will require a lot more work to clean-up. I have to clean the carpet where furniture used to be and there's a lot of dust and long forgotten small toys that were under the furniture.
