I also totally forgot about 2 of the most important things.... Water, and your feet! Do NOT skimp on boots. Try every pair in the store... try half a size up.... try half a size down. Take your hiking sock setup with you (liners and wool socks) and try them using those. Wander around the store a bit...

Sorry, I'm a little late to the party on this one. Looks like you ended up with some great stuff! A couple things I think I didn't see mentioned before: Invest a little more in a sleeping bag. Look at Western Mountaineering or Feathered Friends. Both are very nice down bags that WILL last a lifetime...
