You're in luck, Drunken Zombie, because I am a WoD fan, have STed (Storytelled, our term for GMing) and know some quick nWoD resources to get you started.
First, go to DriveThroughRPG. If you don't have the money to buy the nWoD Core Rulebook (the one with the black ghostly shadow on the bluish street for a cover), download A Nightmare At Hill Manor, which provides a detailed starting point for getting into the ST system. Core rulebook most DEFINITELY has more detail, but these will keep you afloat.
Second, look up the New World of Darkness page on TV Tropes. Read through the tropes to give yourself an idea of the world WoD is set in. This isn't some D&D epic fantasy — it's dark, it's gritty, and it's cynical.
