Well, Reaper, the key things I think you'd need to look at are the classes - particularly, the Fast Hero and the Charismatic Hero. Toose two combined with Hero levels would make the perfect swashbuckker. Combat is sufficiently the same that I wouldn't worry about it. Skim the Skills and Feats. Much is the same as D&D 3e, but there are a few differences. Make sure you take the archaic weapons profeciency, so you can use a rapier. Finally, the Occupation aspect is new. I'd guess either the Adventurer or Dilettante would be the most appropriate Occupations for Jack Styles.
