I think B would be great. I think the eccentricity of characters would reach a different level where you can never be sure exactly what/who you're talking to. That's a highly volatile environment with much opportunity for mysteries and plots...which ya hardly ever see anymore (Least I dont get to see them *sniffles*). It'll be good to have to think again, instead of running around with the toughest char picking fights! I'm up for more knives in the backs and poison! 
Would vampires really have to heat their skin? Or could they possibly deal with not touching peoples? How can you know something's cold unless you feel it?

Vampires would have to to pretend to eat and drink and make their skin seem warm in order to go un noticed, stealing their victims in the quiet hours and leaving no witnesses.. and so on. Could be fun.
