There's a ton of good stuff you can pull from The Dresden Files for a Shadowrun game.
[ Spoiler ]
He Who Walks Behind - Horror
Necromantic zombies - Voodoo zombies/Shedim
White Court vampires - Free spirit inhabiting a physical body
Demon from the Storm Front novel - Insect spirit
Sidhe - Free spirits
There's also a lot of cool stuff to give you ideas as well, plus it's a damn good series of novels (and a half decent TV series with a lot of potential it hasn't quite realized yet).
Oh, and the novel mentioned above is the second in the series,
Fool Moon. The novels are by Jim Butcher if you're interested, and they're widely available in bookstores and some libraries. It's one of the few book series I can think of that's gotten BETTER with each successive novel and much of what I like about the metafiction plot of Shadowrun rears its head in The Dresden Files (though without megacorps and cyberware since it's set in present day Chicago)
