yes they will have a league play and it looks like something else they might be adding or showing. On the PS4 beta when you view a friends gamercard it shows their level and another icon to the left and to the right of it which looks like a spot to show another sort of rank.

Yes, On the beta it is going to be called Arena mode, In arena mode you are going to be able to have each team vote on restrictions on what they would not want in the game of the arena mode for that upcoming game, This is going to be amazing and can not wait, Also I heard rumors that david the game maker is going to let the beta go into the game is released on the PS4 after Xbox One tries it out, This is a non definite though.
