Wow, that is really bad. Maybe the worst I've ever seen. I don't know how big your tool box is but some of the front suspension parts will kick your rear unless you have the correct tools. If you have all the correct tools then you can do a front end rebuild in half a day but hardly anybody has all the correct tools. You are correct, replacing the lower control arm bushing can be a real pain. I wouldn't replace any parts though until I figured out what was wrong. It could just be a really horrible alignment job. If you have a local alignment shop that you trust you might take it over to them and ask them for an opinion. A good shop will know right away what the problem is. They see this stuff all day long.
If you aren't hearing clunking or feeling erratic performance, Id agree with the highlighted above. If you have a pile of receipts and suspension parts are in that pile, you may have good parts. Verify it before you simply start replacing everything.
