MJ, Given that your stays and shrouds are attached at stout and uncompromised structures, I would say you can sail her like you would if she were brand new. Get the rigging tensioned appropriately and have fun.
If you start seeing the deck peel up at the headstay chainplate or you're taking on water through your shroud chainplates, then you have a problem that needs attention.
One good thing about the C22 is that you don't have a fortune invested in her. And even if you get to the point where you can't safely sail her, you can part-out the boat and at least recoup some of your investment. Big market out there among C22 sailors for parts, project boats, etc.
Don't disappoint your wife.
She needs you to make her a home. In the meantime, I'll wager she will be happy to have you spend some time rehabbing your boat if you want to.
