I read your gear list. I thought I'd give a few tips for trimming ounces:
- swap the nalgene with a reused 1-L bottle of water; Aqua Fina should weigh ~1.2 oz, for example
- use a broad tent stake instead of a shovel (dual use)
- leave one lighter behind since you already have matches
- one of those photon lights that clips onto a hat brim is bright enough as a headlamp, and is probably <1 oz; I don't take a full headlamp unless I plan on hiking in the dark
- use spectra line instead of nylon rope, if it's only to be used for bearbag hanging or fixing things; Backpacking Light, Mountain Laurel Designs, or Gossamer Gear should have both hanging line & accessory line, ~1.5 oz/50'

Items that would cost more $:
- lighter tent; switching to something like Tarptent or Six Moon Designs should be 1/2 the weight
- Gossamer Gear or Titanium Goat trekking poles are about 3-4 oz each

The clothes list looks pretty good. I tend to carry more insulation than that, but don't always wear it all. Hope this helps!
