Armwarmers are essential. Best ones I've tried are Assos. They ARE warmer than the other ones I have.....
Legwarmers are a bit of a waste of time IMHO. Of course if you have thermo knickers I can see where there might be a point to them but I'd argue that they go too high up the thigh.
Kneewarmers though - are perfect. You can use them under bibtights when it's really cold (trick I learned when I was a Copenhagen bike courier in a very cold winter) and for early spring and autumn they are spot on....
