Any help on the number/location would be appreciated, I want to make sure I get them all. Also, how much grease should be "squeezed" into each fitting?

Thanks...

I have a 2000 Yukon 4x4 and I think the front suspension is the same. Here is what I lube each oil change:
Upper and Lower Ball Joints
Inner and Outer Tie Rod Ends
Idler Arm (there are 2 zerk fittings to grease!)
Pitman Arm

When adding grease you do not want excess grease to squirt out. I usually give the grease gun two pumps. Keep an eye on the rubber boot at each fitting. You should see it expand. If you overfill, wipe away the excess grease.

I also replaced some of the fittings with angled ones so that it was easier to lube the front end.
