How to maintain and drive a car in a cold, snowy city.

What is your question?

I currently live in a no-snow, year-round, warm city and will be moving to Spokane, WA. Could someone tell me what things I will need to know about maintaining my car in a cold, snowy city (e.g., how long should I warm up a cold car in the am before I drive off? Do I need to clean the car in ways other than just a car wash?) and the type of equipment I may need (e.g., will I need snow tires?). Thanks very much!
