Tom, your weight is only ridiculous if you have really nice weather and nothing goes wrong. The only redundant things I see are the few pieces of blue foam and the second stove. Those items may total one pound. You could use a tarp instead of a tent, but you will lose some warmth held in by the tent. I really hate being cold, or on the edge of being cold, by that I mean not quite feeling warm, but not yet shivering.
If you hit a cold snap you'll be really glad you have the warm clothes. I don't enjoy having to be inside my bag simply because my clothing won't keep me warm enough.
