To answer the second part (concerning chapter two), I believe Larian has said that EA will only chapter one (which we don't have all of yet). I do expect that we will see more of chapter 1 before the end of early access. As to the level cap, I can't speak on that, but I hope we get at least one more level in early access, if only to play with level five abilities
