Questions about Needful Things and The Legion (spoilers, obviously)

Yes, many characters in SKs books are able to do magic, not because they are really magical beings, but because something greater is working through them. Note that when Alan holds out the flowers he thinks "it's the coming of the white" a very strong reference to the DT series right there. This shows us that while he has never had any actual dealings with "The White" he is aware of their presence on some level. The forces of good chose Alan Pangborne to be their instrument in defeating Gaunt, and so he was able to defeat him

As for who Gaunt is, I do not believe that he is Satan, but that he does work for him. He could very well be Flagg, but I don't think so. All previous incarnations of Flagg have the initials of RF, but he could just as easily be a being of the same type, another agent of the Crimson King.

Magic is an essential part of the Stephen King Universe, all we can do as visitors to that universe is accept it, and look for it to show up.

To my understanding, Leland Gaunt represents the Devil..

Flagg was under the alias of Marten Broadcloak and Walter o'Dim for quite awhile in the DT
