B and N toggles are pickup selectors. Series/Parallel switches between one and two coils of the humbucker, respectively, so you've suddenly got a boatload of tonal options.
Still, it appears to me that there are no switches to split the humbuckers, now I don't know if this has been left out on purpose, I just think that with the humbucker splitting option you could have even more sound possibilities. But I am sure there is a reason for that not being there. So I am only speculating based on my little knowledge.
