stick on some sachs. there are a decent brand (well they were anyway before all them companies starting getting their parts made in third world countries to cut costs) so a reputable brand name means f all these days to be honest. if the top mounts and bearings are ok I would leave them on. don't ever renew parts that are still good because you will struggle to find the same quality as the originals. btw the rear suspension doesn't have bearings on it.
