I was in the same boat as you. I believe that you can explore to your heart's content as long as you don't cross a boundary with a warning about progressing the world.
I explored everything in act 2 up to the boundaries, and then did Moonrise and I don't think I messed up any questlines.
It's hard to describe without spoiling anything, but once you get to Moonrise, it does give you some direction on where to go, so it does kinda make sense to go there ASAP.
