Old wallpaper to Old World....wallpaper solution

After 2 yrs of searching for the perfect house, I finally found it. The only problem, if you can call it that, was it was not decorated in my style.  It was a very beautifully, professionally decorated home, but it was more of a "country elegant" style & I prefer an "old world casual" style.  The former owner was not afraid of color & me, well I just prefer earth tones.  After bringing in our furniture & things we realized the dark pinkish red master bedroom & bath just didn't go.  The 1st thing on my list was to paint the walls a more neutral shade of beige or green.  We began with the master bedroom. we primed the walls & then painted. It was during this process we discovered we were painting over wallpaper that had been textured & painted.  I suppose it wasn't a bad idea to do so because the paper was in very good shape & who enjoys taking that stuff down.  However, we found that we had to paint in very light coats and let them dry well between coats.  After this I found out  most all the rooms had wallpaper...ugh!!  Now, on to the Bathroom.  I decided I would try to remove this wallpaper.  It was horrible.  The paper was on there way too good.  I don't think they primed the walls before papering them.  I removed most of the wallpaper & some of the sheet rock paper too.  Now, how do I fix this?  I originally wanted to paint with the Venetian Plaster so since I had it I got started.  As I began, I realized if I used a little more than what was suggested I could actually use the paint as plaster & that would camouflage the damage I caused to the sheet rock. After 3 coats of V.Plaster I then decided to use a coffee stain over it.  The results were awesome!!!  I will be adding more photos later.
