It sounds like you either overtaxed your bearings or unevenly wore your tires out with the poor camber your car is running on those springs. Check the tires for cupping especially around the bald spots. Uneven tire wear can also cause the wheel balance to be thrown off a bit, but if that is the case, dont balance the bald wheels. If this is not the problem, have the bearings, CV shaft assemblies and alignment all checked out and replace those bald tires. They sound like they have seen better days and could be part of the cause for the shakiness no matter what. But the CV shaft wobble is definitely not normal. If it is shaking even a bit, that's a sign to get it checked out. No matter what, replace the bald tires and get the car properly aligned. Let us know how it goes.
