So after she puts his stuff by the curb how long does he have to claim it before she can have it hauled away?
Presumably til the looters have stolen it or the trash collectors come.

Does she have a legal right at any time to sell any of the stuff
No.

She also intends to get a protection order preventing him from coming on to her property after this is all over. Will this take another 70 days?
No, those move quite a lot quicker. She can have a temporary order put into place nearly immediately upon filing, which remains effective until the hearing to have one for a longer term.

The moment he is out, she should go file.
