The layers you mentioned will work, but don't forget a pair of gloves/beanie and maybe thermal long-johns if you're going to spend a lot of time outdoors. Down is warm but if you spend too much time in the rain it loses its warmth really quickly. A waterproof shell is generally more multi-purpose

Best layers on top IMO:-

Tee/base-layer - Fleece jacket - Waterproof shell

Should cover you
