I'm a little lost in where you are in the negotiations.
He has to pay child support and spousal support (is this just temporary, or is this the final amount?)
You are keeping the house? (Can you get it refinanced in your name? How much equity is there in the house? Or are you trying to just stay there until youngest graduates, then split the equity with ex?)
How much community debt is there besides the house? How are you planning to split that?
Seems to me that it's not all that complicated. What exactly does HE want? (Besides a zipless divorce where he walks away with no responsibilities at all?) What did the court say? What is left to negotiate?
