I would normally wear a baselayer, normal running top then a jacket and running tights. Depending on the temperature, I will also wear a wolly hat and gloves.
My reccomendation would be any Saloman shoe. I am not sure of the name but the shoes the girl is wearing on the front cover of January's edition of Runner's World look very good,
When ever I stick my number on I just use safety pins. Nowadays at some events the number actually sticks on to your shirt but that is only at certain events.
