Honestly aside from the warring triad and Alexander quests at 60, there's not too much in the background. But what is there will require you to do the msq to a certain point to unlock it so focus on that. Ask your fc for when you need to unlock the side dungeons for roulette access and it should be a straight shot as each one will provide gear for the next. If possible I would keep potd as light as possible esp for a monk. It's good for exp but nothing there will help you learn your new skills or rotation it's horrible for that
