I'd like to offer a third recommendation for Kim Newman's vampire series. Also Jeanne Kalogridis' Covenant of the Vampire Series is also very good.
If you are going to read Kim Newmans vampire books don't forget to keep an eye out for books written by 'Jack Yeovil', it's one of Newmans pen names and he wrote a bunch of Vampire stories under that name - most of them are collected in an omnibus called 'Genevieve Undead'
