Also, you get your first specialized Barding at Rank 10 (ie Paladin, White Mage, Dragoon), your second specialized Barding at Rank 16, and all three Bardings at Rank 20. However, if you pick say, the Tank barding at Rank 10 you'll be stuck with that choice until Rank 16 or 20 when you can pick the other two. Respeccing your chocobo's specialization doesn't reset the barding you picked. In other words you can have Tank barding, reset your stats to Rank 10 Attacker chocobo, and you'll still only have access to the Tank Barding.
