Mike, the red paint marks were apparently inspection marks...you'll find them all around the chassis (engine mounts, etc). see 8ma1046, esp the 3:31 am entry.

Unfortunately, they only really look right on top of a black bolt....so in the enthusiasm of installing all new, bright zinc hardware--hmm, buy a blackening kit 
Btw, I don't remember seeing those grease fitting on my heims, but (esp since the boots are on, access a pain) suppose that just cleaning then saturating with grease is the right path.
Putting on the boots, not all that hard--if I remember correctly, poke the threads starting at the boot small end and thru the far end, screw just enough into the rod to hold the heim, then just give the thing a big pull (and the rubber stretches like childbirth over the heim).
