Materials not working as they should...

Im having a problem where I cant seem to apply the skinshade material to my subtool. Well, it seems to be applying but when I try paint white on top of my model it will paint grey instead. Not only that but I am seeing these wierd paint/material artifacts on my model (see pictures) Whats going on!?

Ignore the teeth, they are a separate subtool
