I would assume it depends on what you believe. As for 'vampirism', and I'm not talking about a fan-base here, there is a ...subculture on the subject. Drink Deeply and Dream is a wonderful site for information on what I'm talking about. You just have to really look into it and research it.
As for information on spells and such, why not look around yourself and experiment? I am! I'm totally new to all this and I'm super psyched to get started. But I've always loved to learn and do research, so maybe I'm the only one who's over-hyper when it comes to magic/magik.
