No, DO relax.
Lawrence, your wife might be right with you going batshit about all the nuances. Lucky you, she's happy with what she has. I inspect about 4+ houses a day, in various neighborhoods around SoCal (from Santa Clarita to San Diego). A house is rarely perfect. Even the fancy million dollar ones. It may look all good from the street, when you visit or walk in, but folks that live there for 6+ months-40 years in any house notice weird things that bug them. Being as nitpicky as you want to be all at once will drive you friggin' bonkers. You can eventually get to fixing them. Low voltage exterior lighting is a perfect example.
Let me be clear, what I mentioned are not absolute minimums at all. They are the absolute maximum. I am in the home improvement business (plumbing, electrical, roofing, stucco siding, HVAC, windows) and those areas can and will be HUGE nightmares that can amount to 10, if not 20, maybe 30 thousand dollars worth of work if they're screwed up or done improperly. I have seen it, I have heard it from homeowners firsthand while they're pulling their hair out, and that's the type of stuff that makes you regret buying a property immediately.
It sounds like the major foundation items of the house are OK, so chill pill. Along the way fix the stuff that's bugging you, and get to it when you can. But from what it sounds like you bought a good house, and eventually once you get to the smaller things, it will become an ideal house.
