Handling upgrade...what parts?

Like I mentioned before - my ball joint is welded in because its turned its way out more than once. I need to get new UCAs anyway. If I replaced that one, it would be the 3rd one I've used on this car on the passenger side...first one cracked...

Personally, I think the factory ones around are pretty shot...and its a chintzy design as it is. I'm willing to pony up some money for good parts for sure.
