I'm not familiar with the books you've listed, but I do have two others I can list as being fun and amusing, though they're kind of heading in the romantic direction if you don't mind that.

The Hollows series by Kim Harrison, beginning with Dead Witch Walking and the Undead series by MaryJanice Davidson, starting with Undead and Unwed.

The first one is more about a witch who's an investigator with a pixie and vampire as assistants and their various adventures. And then Undead and Unwed is about a model named Betsey turned vampire and... laughs ensue.
