Also, while we're here, should we be combining Good Omens TV and books if both are nominated or are there significant differences to the new show?

I don't think they should be combined. The endings are very different, there are a number of characters who appear in the book but not in the show and vice versa, some of the characterizations for the characters who do appear in both are pretty divergent, and most of the show's worldbuilding re: Heaven and Hell is completely absent from the book.
