How much dielectric grease?
I ordered new COPs from eBay and wanted to know how much dielectric grease to use in each boot. After loading spring into boot should I fill the boot completely with dielectric grease? My plugs have 45K on them. Would you change the plugs too?

Just a little bit on the tip end will be just fine. If you want you can spread a little around the inside of the coil.... Wouldn't worry about changing the plugs till 75k... even though they are designed for 100k service.

I remember how pita it was to replace the ones under the firewall, so at the very least, replace those two. I would replace all of them if it's me.

Being that far into the project I would change the plugs and take comfort in knowing I might not have to touch them for the next 100K miles or so. If however you think you might get rid of the truck before 100K miles, then no I wouldn't go through the trouble of changing them. Of course if you don't change them and the new COPs don't make the engine run better because of a bad spark plug, you'll be kickin' your own butt for not changing them.
