The question here is whether you are bottoming out the rear suspension or not.
One way to tell is to take some child's modeling clay (aka PlayDoh) and put it
on the suspension stops, then go for a ride. If the clay gets mashed, then
you've been bottoming out the suspension. If it is bottoming out, then stronger
springs will help. If not, they will make it worse.
BTW, even full shocks can be worn out.

Very true, but they have more effect on small bumps than on big ones. If it
seems like you can feel every little pebble in the road, that's likely tires.

Sure, although I believe the stock lower bushings are nylon, not rubber. Only
the early TR2 had rubber lowers.

IMO, no. The upper bushings are a lot easier to get to than the lower ones, and
at least in my experience, the rubber "goes away" much faster than the nylon
does (which is why I converted to Nylatron).
