Any paint would do to paint on plasterboard. I have painted many new houses in vinyl matt when painting in south London. Never had any problems. Any painter and decorator in London would agree.

Definately prime the plasterboard first. Ive just spent almost 2 weeks trying to get wallpaper off bare plasterboard and it was a nightmare. The next person to decorate the room will thank you for it!!!

You can also buy a plaster board primer from gyproc or lafarge to aid stripping paper...but it might only come in large tubs.....which may also answer your question about buiders sealing the wall.....normally this is done by the guys who tape and caulk the joints.
