Is there anything in the wiki on how to script NPC's? Or are you talking about the mechanics that need the programmers?

I am talking about C++ programmers who program the game mechanics and program the script bindings which make the scripts necessary for a tutorial possible in the first place.

Regarding NPC scripting: I would suggest you to learn from example. The test.lua from TMWServ got examples for almost everything the script engine is currently capable of. There is a documentation of the current script bindings on the wiki, but this is still incomplete.
