Well assuming brain transplants are possible here is what I would say.

1. If you judge purely based on physical basis than obviously whoever looks like "George" is "George" and whoever looks like "Harry" is "Harry". Of course, if you think about it many psychologists believe in multiple personality disorder so by a purely psychological basis whoever's conciousness resides in a body dictates who it is.

2. Difficult to say, again I would think a soul would resign along conciousness. I mean, you seem to be implying that "the soul" would reside in an organ like the liver or something. Of course if you are talking about brain transplants than I suppose we would be assuming that the soul would resign in the brain. Of course, I would just say they resign along with the original conciousness.

3. By question 2, whoever's conciousness committs the mortal sin would go to hell. I would think that physical appearances mean very little to God. Of course who is to say that getting a brain transplant isn't a mortal sin.
