Tokico HP struts are probably the best strut readily available for the Capri right now. They are not cheap, a set of four will run $350-400+shipping.
KYB GR2's are a little stiffer than OEM, they're cheaper than the Tokicos, but I really wouldn't call them a "performance" strut, but they are better than OEM options
Gabriel, Monroe, etc. all OEM struts, cheap but not "performance".
Strut mounts, that's up to you. These items add up quickly. Personally, I'd inspect them & re-use if they're still good - the rears probably won't be worn at all, they don't see much action. The fronts will dry-rot and crack, and the bearing in them will dry up & start to grind.
Rockauto.com has some decent deals on strut mounts if you do decide to go new.
