If you look at the "adventure" stores, they are having winter sales now. Do you have a Columbia outlet near you? We purchased our midweight baselayers from 32 Degrees, online. We took 2 baselayer tops and 2 bottoms each along with a pair of sweatpants to wear under the waterproof pants. We went with Viking at the beginning of December and they provided the boots and pants for us to wear along with a "puffer" jacket/waterproof jacket for us to keep. You'll need a neck gaiter, winter hat and waterproof gloves.
