To my knowledge, if you play every day, the longest part of Pathfinder Part Two will be getting Revered with the new Legionfall faction. The legion zone invasions won't start until next week (week 2 of weekly quest, I assume), so even if you get revered before next week, you will still need to have defeated legion invasions in the 4 different zones. At that point, you will have had ample opportunity to have all the other requirements completed though.
Edit: I'm pretty sure the Darkmoon Fair will be active next week so that will help a little for rep gains.
