Nope. No lube necessary on the spring/guide rod assembly. Maybe just wipe off any carbon build-up.
No need to worry about the gold compound. I try to remove all of it before I shoot the pistol. Glocks work best with a minimum of oil. A good technique is to coat the slide and barrel with Militec, allow to set for several minutes, and then wipe dry. Do this after your next three range visits. This will coat the weapon and prevent the carbon from sticking to it. Put a drop of Militec in each of the rail grooves in the slide.
Sorry I don't mean to give a cleaning lesson. I was amazed at how well Militec worked when I was told about it.
