I agree. Take a look at the threads here under Tires & Wheels. There are several options in terms of wheel setups (18s or 19s, square or staggered), kinds of tires (studdless snows, performance snows), and brands (Blizzak, Dunlop, etc).
I got 18s staggered with Dunlop Wintersport 3Ds and they've been great so far, especially on icy snowpack. And they're quite quiet and fairly sticky for snows when on dry pavement.
Washing is another matter. Deicing chemicals and road grime end up coating your car quickly. Seriously consider a clear bra for your hood, fenders and mirrors. And plan on investing either in regular expert hand washing/detailing (including undercarriage) or materiel to do it yourself, because that grime won't come off with a touchless spraying and you don't want the run-of-the-mill car wash doing a sloppy job and potentially scratching your finish.
