The civic diplomacy trainer is the one you need to speak to and your probably already accomplished that by going through his little dialogue. You should have 2 quests right now, one being the quest to gather 2 hearsay. The other quest is only completable after you have completed all the other parts. Do the hearsay quest and that will update 1 part of the other quest, then get the next quest, do that and then the 3rd one as well. After you complete all 3 subquests you will have completed the main quest.
