My cold weather layers depend on how cold it is. I start with arm warmers and knee warmers, then add a wind vest, then...

For really cold weather, I wear Pearl Izumi AmFib tights over my cycling shorts. If it's cold but not really cold then I wear a lighter pair of tights. I use the same cold weather layers for fast-walking in the cold too, so I don't want a chamois in my tights.

On my feet, I always wear SmartWool socks. My shoes won't accommodate multiple pairs of socks, so I use a shoe cover. On really really cold days, I add a toe warmer - you know, one of those (unfortunately) disposable things that generate heat as soon as you peel the backing off of them. They are supposed to be placed on the bottom of your foot, but I don't like the feel of them there, so I paste them on top of my foot - actually on my shoe - with the shoe warmer covering it. Nice and warm! I get the warmers from REI - you can see what I'm talking about by doing a search for Heat Treat.
