Which cards [...] get?

Paladin and buccaneer practically falls in the same area as warrior set. The more funded you are, the more likely Max crit would probably help you since you already have tons of crit anyways. I'd go for for a thief or pirate set and resistance set before worrying about buccaneer or paladins. The boss damage and attack bonus from SS set is a good enough reason to keep it even if warrior set isn't that big of a bonus.
