Improve my social swashbuckly pirate.

Have you considered Duelist levels -- at least 1 or 2?

Your damage problems will be reduced even further by the bonus 1d6 from precise strike.

One of the dualist abilities requires you to not have something in your off hand, which is counterintuitive to 2 weapon fighting that the Dread Pirate gets (for reasons unknown as far as I can tell). I have a character who might see if I can get the GM to let me substitute a different feat for that one once he actualy gets to Dread Pirate
