Shiff, for most of that your best bet is going to be connecting with Leanthar. While some of us around have smattering of informations here and there (and certainly a few people who've been here a lot longer than I have and know lots more pockets). However, for all the beginnings of this, L has the information from table top creation to starting with NWN. I think Ed and Orth and OneSt8 would have more perspectives on the early NWN days with Dorg coming in a little bit after that. All of those guys have a significant amount of information about things from Version 1 and forward.
I have no idea how indepth you're going and what kind of perspective you'll want to include but there are certainly a number of currently active players who can put a bunch of perspectives in from perhaps early V2 and forward. It might also help if you have some addtional questions you want answered posted up for people to take on.
As to what the future holds, that might be a little while in coming though you should feel free to raid the dev log and Writer's Wednesday posts and all of that for info or sparking some questions you might want answered. Oh, also the ask and FAQ threads in the MMO section perhaps? Open ended 'what's going on' is going to be somewhat difficult to answer, at least at the moment. There are legal bindings for some of us (NDAs and such) and again, not certain the depth and scope of answer you're looking for.
Hope that helps you get started.
