What happened if you killed Arundel, for instance?

I don't think anything happened, but you were probably screwed if you planned to continue the game. In IwDII, the game will end (similar to the whole party dying) if you kill Nickademus before your done with him. Also, if you kill that Yuan-ti priestess (can't recall her name) outside Dragon's Eye, you won't be able to enter. In fact, there are a lot of fights in the game that wont let you leave the area until they are finished. Overall, the game is pretty good about letting you know when you screw up, but I would make sure I knew when I was done with an NPC before killing him off.
