Socially smarter doesn't mean better social skills.
It simply means that they are more socially aware. If you allow the metaphor, I would say that they are more likely to "play the game" and "play it well" at that.
Social skills have very little relationship to "emotional intelligence", so I have no clue why you would bring up the point that women are more willing to talk about their feelings.
You are comparing extraversion and agreeableness. While both are statistically higher in women, you are comparing apples and oranges.
