They developed the concept of the world. so the Ivalice setting, the story and the characters. this is because Ivalice is their world, they've developed this world and its concept and improved it from previous games. i asume the Gamit system was also based on their strategic roots in Tactics Ogre and FF Tactics. but it was Hiroyuki Ito who directed the combat side of things.
other than that, anything else is speculation on my part. although i would have thought the Playonline team had mostly programming duties. i'm sure theres information floating around based on the post-morterm they did of the game. so i would take a look at that if your interested.
