There is a greaseless chain lube used on motorcycles that makes an excellent lube for these hitches and you don't get grease all over everything. I have used it a lot on different hitches and even on my motorcycle!
The purpose of the bars is weight distribution, not sway prevention. The friction bar with the tightening lever on it is what prevents/stops sway.
Equalizer makes a sway bracket jacket to reduce noise. I haven't tried them so can't say how they work.
