You're carrying too much stuff for that pack, which is a few ounces too heavy for a frameless pack to begin with. You'll also want to dump the neoair for a foam pad if you are using a framless pack.
Nice tent, but you can get by with just a tarp on the JMT because you'll rarely want to sleep in a tent to begin with. It will be ncie for moquitos though. If you go with a tarp, pack a bivy, bug bivy, or headnet for the skeeters.
Loose the pillow and use bunched up clothes in a stuff sack.
You can go to down for the bag and save a bunch of weight, but it'll cost you.
Packed clothing looks good, but missing the gloves, shirt, socks, shirt, and underwear. All things you'll want.
Cooking looks good as well. Made yourself a windscreen. The wind is really bad out there. It'll make your fuel last much much longer. You can go alcohol for simplicity, but the fuel will be heavier over a longer trip, so it's just about a wash.
Loose the filter and go for chemicals. I used Aqua Mira and I've been a convert ever since.
Good call on the two batteries.
You probably won't need an ice axe, but it does allow for some killer glissades.
Sunblock is mandatory, as is a sun hat of some sort. I used a headnet and never needed insect repellant.
You WILL want more than 1.5lbs/day. I was more like 1.8 and I walked into every resupply place hungry and eating my last snickers. After 4 days your hunger will become immense.
Cross trainers are fine. I used trail runners. Just make sure you have a lot of traction. The mesh is good because it'll be hot and maybe wet, but it does let a lot of sand in.
From Whitney Portal to VVR I carried 10 days of food and I ate it in 8, just as I was arriving. No, it probably won't all fit in your bear can. I used the bear boxes for the first 4 nights. Really really plan hard and practice at home to get everything in there and I bet you can do 9 days or so. Remember, day one food doesn't have to fit!
Enjoy! Best trip I ever did.
