On your last remark about the Grail: you mentioned that you didn't see the Grail being taken up to Heaven along with Galahad because Heaven has no need for things. Actually, in the medieval romances where that happens, the reason why the Grail is taken away to Heaven is that humanity had become so utterly corrupt that God decided that they had become unworthy of having the Grail with them. (Although that was only a relatively late development in the story; in the early Percival versions, it does remain on Earth).
