I'm planning to play New Vegas and I'd like to get some suggestion for the build I thought of. I only played Fallout 2 before so I really have no idea what can be useful in the game, so I'm hoping to get some further suggestions:

Strength: 4
Perception: 5
Endurance: 4
Charisma: 9
Intelligence: 9
Agility: 5
Luck: 5

Tagged skills:
Right here I have a problem with deciding between: Speech, Medicine, Science and Repair (possibly guns)

Traits:
I really have no idea, but some of the ones that sound interesting to me are: good natured, small frame, four eyes, skills

Perks (first couple, later I'll go with my intuition)
Here I'm open to suggestions, but I'd choose from some of these: lady killer, intense training (cha or int), educated, comprehension.

I'm basically aiming for a diplomatic-sciency guy, who can talk himself out of most situations, without ever initiating a fight (of course self-defense is another thing, he's not a pacifist ). I usually do play charismatic guys in rpgs because I want to experience as much dialogue options as possible and basically different gaming options.

So basically, what suggestions would you have to this build?
