I live in the northeastern part of the Phuckeye State, and the only reasons I put my bike up for a couple months each year are salt and ice - mostly salt - I hear ya' there. It'll tear stuff up quick, on a bike.
If you get some good dual sport style tires, then you shouldn't need worry much about a little snow or slush on the roads. Ice is the real killer. If you wanted to take an extra precaution, you could put a few angularly alternating screw-in studs down the centerline of your rear tire. There are some thread over on ADV that cover it.
The Dunlop D616 is a good front tire in the "stock" size for that kind of thing. There are tons of rears available, since the 150s work very well.
As far those tire chain things go, those would be last ditch. You wouldn't be able to go much faster than 20 mph without a serious chance of those things breaking-off, creating an even worse situation. Plus, they're only good if there's already a few inches of snow on the road. You'd be better-off waiting for a vehicle to come along and break a path.
I find you have to plan to be "flexible" when riding a bike during the winter months.
