You need to speak to the realtor and find out how much of a loss was taken. If he truly wants you to sign off on these papers, I would negotiate any and all expenses for repairs and cleaning of the house, as well as his tools be wiped off the slate. That's much more doable then the other items you want right now.
As for the other items, well, those can be negotiated during the hearing. He already knows what you want in those areas. They can be negotiated during the hearings, etc. coming up.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
