I would suggest going through the house ahead of time and making a list of what you really want, what you would like and what you don't care about. That way you're more prepared for the sit down and you can propose a place to start.
Some rules I had were: 1) If it was a family item, then it went to the one who's family gave it. No reason you can't be the one to give your S or D the china after they get married. That way you ensure that it will stay in the family. 2) The kids stuff was split 50/50. Meaning if something needed to be purchased, then we each had to buy something. Like, take one bed and both buy another. 3) If I wanted to upgrade anyway, I let him keep the old one. But I didn't mention that I wanted to upgrade. That was my little secret.
By the way, I'm assuming that she is keeping a car. She doesn't just automatically get the value of her car in stuff. It should be the difference between the value of the cars to whomever benefits.
