Replace 1 bushing, or everything?

Got my car up in the air again to replace the torsion bars, and I notice that the LCA bushing is pretty much blown out on the passenger side. I should have noticed it earlier, the wear on that tire is really strange ("cupping" I guess would be the technical term). My question is, since I'm already replacing 4 shocks, leaf springs, torsion bars, an LCA bushing and at least one inner tie rod boot that's cracked, should I just go ahead and get a full front-end kit and replace all the bushings and everything? I want to do things right but at the same time I don't want to just be throwing money around without reason. The UCA bushings and ball-joints look okay but I still need to see if there's any play there. Sway bar bushings are definitely old and have some cracking. Haven't had a look at the strut rod bushings yet.

The more I type this up, the more I feel like I'm answering my own question and I should just get new parts while I'm doing the work. Never hurts to get other opinions, though. If I get a kit, any thoughts on PST vs. ESPO vs. something else? Is it worth 25 bucks and finding a friend who can weld to box off the LCAs? Or should I just take things apart and decide afterwards based on how stuff looks?
