LiFePO4 balancing question

Before my charger timed out at 120 minutes, I had two cells at 3.6v and the third at 3.35v. I was charging at 1amp and this is the first time I've ever charged it. Can I continue to charge the pack? What do I do about the unbalanced cell? The battery is a turnigy 4500mah 3s LiFePO4 and the charger is an iCharger 208b. Also, how do I check the capacity of the battery pack?

Thanks
