Larian has a handful of tutorials from the DOS1 days that will help with much of the basic stuff you're talking about here. What they don't have is the scripting, NPC, and questing info that Windemere has been covering!
Yeah, in one of the videos I explain why I didn't do much with level design. Like Rawss says here, there is already a fair amount of information available out there on that. I could and probably should link to those videos though, so thanks for the feedback.
