As for W's version of CS, well that is just their opening position. Obviously you will not be paying that much, but it will be good for a laugh with your lawyer. (Unless that is your contribution to the total--was her contribution listed as well?) You need to ask your L if there is a formula that is used in your state, and what the parameters are.
As to the household furnishings, I'd take a "whatever" attitude. In my case it was odd that XW insisted I take our master bedroom set. Particularly since when I moved out, it was into a small apt for a "trial" separation. Later I realized that when we bought it, it was one of the few times I took her up on her offer to find something "we both liked." In other words, not what she would want for herself.
The other thing that was different, in the two months before I moved out she would not sleep in our bedroom, no matter how much I offered to sleep on the couch or fix up a bed in the den. In your case, since she is the one who wants this divorce, why are you the one sleeping on the couch?? If nothing else, can't it be her turn for a while? 50/50, right?
