Joann, I've gone thru the same thing with a small master bathroom. No easy chore, but do-able. I also had a lot of drywall paper come off with the wallpaper, as careful as I was. But that is an easy fix than tearing out all the drywall and installing new. Do a (ctrl + F)search on wallpaper and/or sheetock. There's been plenty of discussion on this. Also, I'm sure some pro's will be along soon to help.
