For a first time playthrough what would be a good choice to have a fun experience with good social skills for dialogue and at least one dependable combat skills so I dont get butt raped in the Sewers?
I am leaning for a Toreador pretty boy so I can do a second run with a Malkevian or Nosferatu chick
A Frequently Asked Question, to be sure.
I always recommend simply doing the quiz method for your first Bloodlines character. It sounds like you already have a type in mind, so you'll probably end up with something that fits.
If you have a specific idea of what you want technically, then Toreador is a solid choice for what you describe. Most of the combat is easy in the beginning (meaning you shouldn't have much of a problem no matter what you do), but if you build for firearms, you'll start to get access to some powerful weapons by the middle of the game. The guns you get in the early game are weak, but it shouldn't matter much.
Another possibility is Ventrue. They have extra dialogue options from Domination and good, generalized combat disciplines.
