7 scripting questions i need help with

[Gamemakingdude]

I have 4-5 scripting questions. If you could guide me to what procs i should be looking at then i think i might be able to figure it out from there.

1. Sets say i have an area and it triggers an hanged prisoner to start moving around (like swaying) I want it to do either of the two things...
(a) To move to another place
(b) Start moving around (like a wind hitting it or something)

2. I want to make an collision event when a certain item hits an enemy (say a knife hitting one of the brutes) how would i do this?

3. I have an insanity area set up and i want a note to appear from above and it would fall to the ground (any ideas)

4. Is it possible to give preconfigured items (say agrippas head for example) and give them different names and description?

5. How does nodes work and how do i make them work for the enemies?

[EDIT]

6. Is it possible to pick up other items that aren't usually picked up (may be question for fritctionalgames.)

7. How do i add quests after reading a diary or trying a door?
