Breeding an albino to a normal will give you hets (unless the normal is already a het... hard to tell unless you breed her). Breeding hets back to the father should give you 50% albino, 50 % hets.

Sorry for the poor diagram.
As for the weakening of the species... this is a whole can of worms so I won't go into depth. I, personally, believe that one or two inbreeding is fine. More then that and I say you're weaking the species (indicated by kinked dails, deformed eyelids, blindness, ect). I don't really want to argue the issue here but those are my beliefs and, from what I've read, somewhat agreeded upon as symptoms of inbreeding.
