OK - from my knowledge and recollections:
1) Certainly - I've had an old track type spotlight rigged to a 12v lighter plug for years in my Blazer, it's the world's cheapest roadside trouble light[img]images/graemlins/wink.gif[/img]
2) Any trailer plug set will work, or for really spiffy, you can get a GM weatherpak connector set at any auto parts store.
3) Just take your old one in - there's only 4 or 5 "standard" sizes for pin switches, and any parts house will have them.
4) The easiest way to do it is to use relays, and use a switched terminal (get a test light and experiment - there's several) to feed the switch legs of the relays.
5) Use what you like - as long as they're through relays and not hardwired, any switch is fine.
6) Great idea - I've got a keyed switch (old Cat ignition switch) for mine. A little extra security, but not necessary. You could actually use a 59 cent 110v switch for this purpose with no ill effect.
7) I had a set like that with my OEM bumper - I took the mighty Sawzall and cut a pair of holes in the front of the bumper, then mounted them inside the channel. They now live with whoever it was that stole my %$#@ing bumper [img]images/graemlins/crazy.gif[/img]
8) Easy as pie - You'll need the following:
Steering wheel puller
GM lockplate remover
T-15 Torx screwdriver
About 1˝ or 2 hours
Here's pictures of my Blazer's torn down all the way (Same GM column as a YJ uses) http://community.webshots.com/album/17272977QOQEcrhPHn
