Not sure what to tell you. I do all those, obviously, I live in a place where I also experienced -25 for couple weeks straight straight (and never anywhere close to -40). Agree on clutch and LCD, agree on not using washer fluid and scraping the windshield properly, and I'd add on lift your wiper blades now that the sun has some heat as your wipers will easily freeze on top of the mini-greenhouse that is your dash. But if I hop in my car and drive away immediately, the windshield will be foggy before I've gone a km - regardless whether I have the compressor (defog) on or not.
