Not too sure about that there, sorry. But there IS a way to remove the main menu loading time, intro and the developer/publisher cutscene at the beginning. Check here for more: Dark Messiah No-Intro Mod (by Zakola)
RAWR ! You can't.. Because it would destroy the game engine is some way, The Cinematics okay,But if a NPC is bragging and blahblahblah you can't,In Cinematic just press ESC i think.! :)
Yes, that helps in skipping too. But that's probably basic, and known by everyone :P.
