Use whatever you consider expendable. If it's an older 9spd set up you have lying around (something you're not going to miss in the spring), go for it. Otherwise, think about a singlespeed rig. The slush and salt on the roads around here will leave your derailleurs and cables in poor condition very quickly.
For the front der., measure it with a caliper or bring it to your LBS and they'll gladly point you in the right diameter direction.
For the rear der., take the difference between your chainrings (large-small=x) and add that to the difference between your large and small cog in the rear. Every derailleur will have it's own specs- a short cage will usually accommodate up to ~22T total difference; long cage can do up to 44T.
