Ken,
To add a bit of controlled friction to your wheels to limit the landing roll, you can try combinations of nylon washers, Teflon washers, Buna O-rings, etc. between the wheel(s) and the collar(s). You can still have a bit of play, while putting the friction element on the outboard side of both wheels. Thus, if you add more line tension on rollout, you get more friction.
The concept becomes significantly more important in the wind.
As far as noise, no one wants to listen to screeching wheels (rusty setup; bad combination of materials; no lubrication), shimmy and wobble (crooked setup; out of round wheels; soft mounts), and so forth. Some will say a judge should ignore all that. If I landed a full size plane that sounded like that it would go straight into the shop--the plane wasn't right and neither was the landing.
