HELP... Door panel disassembly hell.

Question 1.
When I go to put the doors back together, what kind of nut or other option do I have instead of these? I don't see how these would go back on. It's like they are compressed and they dont have any thread and the screws are plastic.
What's with all this plastic?????
There has got to be a better way and why did GM use these?
I can't believe how long this took me. I'm pretty PO.
Question 2
How do I disconnect the door control switches from their housings? I've been trying to use a flat head screw driver and I swear, I still haven't been able to get them disconnected.
Qestion 3.
How do I get the two clips holding the trim ring in place on the underside of the shifter ? I got the rivets out but I'm stuck on what to do about these clips.
I can't get them to budge.
Are there any pictured tutorials on the complete removal of the door trim pieces ? I could have probably saved myself hours if there is.
Someone, please help.
Thanks.

Sherry
