Also, if you've got a safe place to store your bike that's not insulated (I can lock up my porch so the bikes are safe, but the porch is uninsulated). The major damage that can happen to your bikes occours when the bike goes from way sub zero temps to indoors temps and back again. Winter up here in the north (another 6 hours north of Chi) can easily hang out about 35 degrees colder than your freezer in your kitchen (before the windchill, which obviously doesnt affect bikes) so rather than let my bike fluctuate back and forth from -5F to 70F I just keep the winter ride cold all the time.

Oh yeah, get your drive train waxed and Nokian puts out a rad (but expensive) carbide studded tire.
