I'd just keep Leveling till ~L18. Get a bunch of LP and get tons of augments, and make sure you have plenty of Phoenix Downs and Potions before you fight him. The first time I fought him, I thought I was dead; I ended up with Vaan casting Protect on everyone and Ashe spamming Cure while Balthier attacked. =P

Also, if you're chaining Imperials, watch out for the Mastiffs! They'll break teh chain. >.<
