That was a pretty smooth move on not looking at the list in front of her. I bet that had her scratching her head.
I think it is very reasonable to ask her to commit to a certain time for the "pillage". As for asking her not to trash the place, you would think that she would be considerate enough not to do that, but if you need to mention something like that to her, just be careful of your tone and how you present that to her. If she feels like you are being condiscending to her, it will probably pi$$ her off and she will end up trashing the place any way. So, be careful w/ that or don't mention it at all.
I think it is good that you are going to deal with the house/mortgage issue head on. She has to know that her name is on that house and that it is difficult for you to pay for it alone. It's not unreasonable at all to present this problem to her and have her help you come up with a solution. I'm glad you are going to do that.
I don't think you necessarily need to get "her" stuff ready for her to move unless you want to. If there is a bunch of her stuff that is in the way and you want to start making a pile of it, you can, but don't go out of your way getting things ready.
I don't think you should do anything about the key or the locks right now, unless you don't trust her for some reason. It may come in handy for her to have a key-- say you are out of town or at work and your D has left something at your house. W can easily still get in to get whatever it is, etc. Plus, you don't want to make the break w/ your W that clean yet, do you?
Sounds like you are making it a fun day for yourself!
