Does he also get to stack Natural Armor bonuses such as the +4 size bonus for transforming into a large creature?
A size bonus isn't a natural armor bonus. It is a size bonus.
As Lady-J said, bonus of different types always stack.
And to add further to what Alderic said, barkskin does not add a natural armor bonus. It adds an enhancement bonus to your natural armor. So it stacks with your existing natural armor.
