re gloves, waterproof or not, I figure the main thing is that if one is going to ride in fall conditions, and it could be very cool and rainy, you'll want to think of something that will help keep your hands warm, because its pretty miserable is your hands are freezing and wet.
I went with dishgloves because they were available (ie in the house) and pack rather small and light.
I'd recommend not tight so that you can put a pair of thin polypro or wool gloves inside them.
They will be clammy, but better clammy and warm and being able to feel your fingers and make them work.
