Your edge issues are a little strange.. It sounds like a premultiplication issue to me. I would be interested to pull it into Nuke and apply a premult to see if that solves your problem. You could do as Steve suggested and erode your alpha a little, which isn't ideal but would probably be un-noticeable...
