We removed some paneling (one wall) in our living room. If it's not glued down, it should come off very easily. If the surface behind it has never been painted, make sure to prime it first with an appropriate primer. If it has been painted, it can't hurt to prime it anyway. Ours was unpainted drywall, but we bought a primer that can be used on painted or unpainted surfaces so we can prime the whole room and then paint. Oh, and don't forget to fill in any nail holes!
