New shocks aren't that expensive should the old ones be shot already. You can get KYB's. They're inexpensive and they're the same guys that make the original shocks for major manufacturers like Toyota, Mitsu, etc. Cruven is a good shop for things like tie rods, etc. But I usually buy new shocks instead of having them refilled.
The other suspension pieces will mostly just make noise if not addressed. If they aren't noisy, your handling isn't funny, and your tirewear is not uneven, I don't see any reason to replace them.
Undercoat is a good insurance against underside corrosion. If the present undercoat is still good (no peeling, no bald spots, etc.), you can probably hold off adding another coat for a while.
Let's wait for the other Tsikoteers to wake up and chime in.
