If you're trying to throw down the miles, read on, otherwise ignore my post.
Eliminate the rain pants. Your legs will stay warm while hiking. Thru hikers sometimes carry them as alternate clothing while doing laundry, but that doesn't apply for you.
Eliminate the thermal bottoms. If you start hiking when it's early and continue until it's late, your legs may only be cold for a few minutes. Also, thermal bottoms take a while to get out of, which means you'll still get cold. Thermal bottoms are nice if you need to urinate during the night, but a potty bottle can be used in your tent without fully exiting your sleeping bag.
Add a hat. The sun up there is brutal.
I wouldn't bother with a tyvek wallet. Just use a ziploc bag. It's cheaper, easier and probably lighter. I'd also leave the toothpaste at home and possibly convert some of that weight into more tp. Only use titanium hook stakes, I think those work better in that area due to the rocky soil...and there's plenty of rocks to put on top of your stakes.
I didn't see footwear on your list. I would wear mesh shoes and not bring any sort of sandals for camp. That does two things: less weight and encourages you to walk straight through the creeks instead of wasting lots of time changing into sandals or looking for a log...especially since the crossings should be pretty easy by now.
