Gloves: 3x unlined white leather work gloves with plain wool gloves inside.
They work great; I didn't use mittens at all this winter. I like the white
color because the cars can see my hand signals at night when I commute
(I think). I bought em from mproline.com, Minnesota. Cheap.
Shoes: Another pair of Shimano MW-80's except two sizes bigger. I think the main
requirement for warm feet is having enough space for thick socks without
compressing them and thus defeating their insulation properties. I think any
boot or shoe with enough internal volume that fits will work.
Inner tubes: Got rid of the butyl, changed to Challenge latex on the theory that the
heavy butyl tube has high hysteresis in cold weather. My commute times
with the latex are all down, but I dont have enough data to say it's
significant or not. The bike seems livelier though.
Clothing: Pearl Izumi white farmer-johns. Certainly more visible than black in the dark.
More aero than my other winter clothes (I have a long ride and it's always
upwind). This was about the only low-drag stuff I could find that isn't black.
