The clunking is probably control arm bushings. The arms have a sleeved rubber bushing that a bolt goes through to hold it to the car. The bushing absorbs a lot of vibration and stress and is what gives the car it's smooth muted ride. When the bushing gets trashed that compliance is gone and you have a sloppy fit with the weight of the car riding on it.

A misfire would cause a very obvious loss in power for as long as it lasts. They really don't get mistaken for anything else. A random misfire now and then will go unnoticed but will not make any noise or anything else.
