Winter Storage

I know the basics, I've got fuel stabilizer and a full tank of gas. I'm gonna move the car around to keep the tires round. I'm wondering about best practices for running the car. This is my first gdi motor. I've noticed people no longer recommend idling your car to warm up since it'll run rich and increase deposits. I would imagine I still want to run it every couple weeks? Even doing gentle revs I have a hard time getting up to operating temp. Thoughts?
