the skullcap is inside the head, so you will need to either scale it so its outside the head, or use magnets, whichever works best. as for the hands and other body parts, thats easy. choose the body part (say hand) and check collision detection, then to apply that to all the fingers and bits, click apply collision setting to children. generally it is a bad idea to have colliison detection set on the head (I use low-res spheres positioned and scaled to the general shape of the head(ensuring that no part of the spheres are touching the skullcap so you dont get calculation problems!)
