if I bred a fire to a albino Id get normals/fires het albino?
You would get fire het albinos and het albinos (Those would be
100% het)

Then if I re-bred a fire het albino to another fire Id have a chance of normals, fires and possibly something a little interesting?
You would get 25% BEL + 50% Fire + 25% Normal and all those would be considered 50% Het Albino.
