The key to staying warm in the wind is to simply have your "windcutting layer", weather it be a windshirt, rainjacket, etc, as close to your outer layer as possible.
The most effective is when its your outer shell.
The further in you cut the wind, the more insulation you lose!
So in other words, if you wear it under a heavy jacket(wool, fleece,etc.), you are pretty much render that layer useless.
As far as noise and raingear, if its blowing hard enough to worry about keeping warm, they aren't gonna hear the bit of extra noise.
Highpoint, Is there something specific you want answered?
