Hold on a second, some of your answers are completely wrong. Jarl Balgruuf is replaced by Vignar Gray-Mane if you choose Stormcloaks and he stays if you choose Imperial Legion. If you side with Stormcloaks you are not a Thane anymore but you have to do one of those lame Thane quests to get it back. Imperials are still Thane. EDIT: Also, Severio Pelagia dies in the battle.
