Looks good to me.
On the water filter note, I wouldn't carry one. I've always thought that the sources are so good that Aqua Mira drops alone were good enough- if they're even necessary. For cooking I just used boiled water and AM for drinking.
The only things I'm carrying that are much different than you (weight-wise) are:
1. Shelter: Shangri-La 3 (23 oz.). Last time I was on a longer Sierra trip I hit 3 days of serious rain/storms. I had a small tarp...that really sucked for prolonged rain. I decided to carry the Shangri-La this time; a total 1 man palace in bad weather- lounging, cooking, etc.
2. I'm carrying less sleeping pad: GG Thinlite with a GG Niightlite. Saves ~10 oz. over your setup, kinda makes up for the shelter weight.
3. Golite Jam2 pack. Something a few ounces lighter might be nice but spending money to shave a few ounces off a perfectly good pack is silly to me.
4. Clothes: aside from worn (t-shirt, running shorts, hat) I don't carry spares except one pair of socks. Packed clothing: Driducks suit (doubles as wind shell/mosquito protection in camp), patagonia Cap 1 top and bottoms, Montbell Thermawrap jacket, thin gloves, balaclava, headnet. It seems some of your clothing is redundant- but at your low weight, who cares if it's how you're comfortable?
Forgot to mention; I'm referencing the gear I'll be carrying for the JMT starting July 1, 2010.
...still waiting to find out if an axe might be prudent for early July. Last time I brought one in July it was a glorified potty trowel...but that was a lighter snow year than 2010. But the July a few years prior had a few spots where one would've been nice (Forester Pass early morning).
