Your quote for ALL the standing rigging looks pretty good, esp if that's installed. It would not include any costs for lowering and reinstalling the rig, I'm guessing, and you might want to do that for a thorough inspection of the rest of the rig while you're at it. If indeed you have cracked swages this would be the right thing to do at this time.
It will a give you good peace of mind for the future
