Lock washers on door handles?

I ended up pulling the whole door part today upon discovery that the door handle was quite loose and that the lock mechanism doesn't lock. The lock problem was easy to fix once I was able to wrestle the chrome window sash an window glass out of the door (holy crap what a pain). The door handle looks simple, too, I think it's just a lack of lock washers that allowed the nuts to work loose. The rubber seals on the handle were shot, one of them crumbled, so hopefully I can order replacements for those.

Another thing I found was, the handle I worked on sat too close to the paint and had tapped on the door enough times to wear through the paint. Do I need to/should I put spacers in there, or was it the failed rubber seal that was allowing the handle to sit too close to the body? Thanks, guys.
