I'll answer your questions as you asked them.
1) You do not have to recapture the depreciation on the appliances as they are not real property and are fully depreciated.
2) You do not include the price of the appliances in the basis of the house. You purchased them separately and got the tax benefit from them.
3)The appliances are being sold as part of the whole house. Just enter the information for the building and leave the appliances out of it.
