I personally think it's Obito because Obito was all happy in Kakashi Gaiden, and so is Tobi. They both have a cheerful nature. They both have the Sharingan. They both look like they have only one Sharingan, because Obito gave the other to Kakashi during Kakashi Gaiden and Tobi just isn't showing the other side. So yeah, that's what I think. This is all just quick speculation. No information from outside my very big head.
2. Tobi is the leader. It was revealed that the so-called leader of Akatsuki, the guy with the piercings and everything, was taking orders from Tobi. I think this was clearly shown to everyone near the end of Chapter 364.
3. Kakashi Gaiden might describe a few things, but not all of them. Kakashi Gaiden is the only prequal that I heard of, so I don't know about that.
