Going off of memory, haven't been deep into a dizzy in a long time.
1) I believe it's heatsink compound. Should be a little packet of white goop that came with the ign. module. I just use a little rubbing alcohol on a cotton ball, clean up the mount area and re-apply. If you don't have any, auto parts store should have it, or someplace like Radio Shack. I've used the stuff for computers before, all your looking to do is aid transfer of heat from the module to the metal base.
2) This is where the memory comes in... I believe there is a felt washer, but I think it's covering a small "well" of grease for the bushing. Silicone based? maybe?
