Going to poke through the rest of it though, as I'm always interested in new information, especially if it pertains to fuel economy.

I always use anti seize when replacing spark plugs and have ever since I had a plug seize while trying to remove it. Even though the threads were full of aluminum from the head and I had to use all my strength to remove the plug I was able to take the old plugs and re-tap threads into the head and continue using the car without having to replace the head. My fix lasted until I quit using the car probably about 10-15 years later. Once I feel the plug seat I give it just enough to snug it down. I've never used a torque wrench when changing plugs although maybe I should.
