What I would do is, wait until the walls dry. Then sand them lightly to remove any glue or scraps of paper remaining. Give the walls a coat of drywall primer. Kilz might be better to hide the brown paper. The brown may bleed through if you are using a light colored paint. After the walls are primed, it will be easier to see the places that need to be filled in with joint compound. Give them a thin coat or two as needed. Since you are using a textured paint, the walls don't have to be perfect. Just address the bad areas.
