Since I've observed no slop in the steering at all, and it is very crisp, I believe the LCA bushings or balljoints must be worn.

I have not replaced any suspension components other than the rear shocks after I bought the car last year. Front shocks rebound fine, no leaks. LCAs look old. Any way to tell for sure? If I do LCAs, should I also do the track arms?
You'll probably find that the tuning fork bushes are worn and tbh there's no real way to just visually check them. When i replaced mine the old ones "looked fine" but you could virtually bend them in half with very little effort at all.
