What I'd do differently:
-I don't need socks and a liner both. I would probably just wear the liner.
-I would ditch the insulated shirt for a light puffy; If I really wanted a sleep shirt, I would have a lighter one
-I wouldn't take both the nylon shirt and a windshirt
-I rarely take rain pants
-Add a pack liner
-There are much lighter options for a rain jacket(dri-ducks, poncho, OR Helium II, etc.)
-I would add lighter, soap, headnet, Deet
-Looks like you are wearing two base layer tops
-Do you need a bivy under your tarp. I have a tarp of about 8x10 and will hardly ever carry a bivy too.
-That pillow is a hog; you can find one for about 2 oz.
-If you make those reductions, I would consider a smaller pack. You could save a pound there as well and I've never loved that pack.
I hope those are useful thoughts, anyway.
