I see the low hanging fruit as the camera, since I use my iPhone as a camera. Not sure what your timeline is, but on my iPhone 4s I get 7 solid days of power on airplane mode with brightness turned almost all the way down and a dark wallpaper.
I'm not a wind shirt wearer. Personally, I'd be okay in the long-sleeved power dry shirt hiking in cool windy weather. If it were too cool for that I'd probably wear my OR helium 2. If I were doing the Wonderland in late July, I'd be hiking in short sleeves, though. It's been really warm here lately, and has been all through the spring.
Regarding bugs: some camps are buggier than others. For the weight, I'd bring the headnet and a .5oz picaridin for cooking, or while at camp and not in your tent. On the move you should be okay.
I would take either the buff or the beanie, but probably not both for this time of year.
Only you can decide if your cocoon pillow is worth the 3.52oz vs using your puffy/other packed clothing in a stuff sack. Similarly, the booties seem like a comfortable luxury rather than necessity. Your choice!
The e-lite will be fine if you don't need to hike and find your way with it and are just using it around camp. You won't really need it from 5:30AM until 9PM. Northern latitudes plus summer equals long days!
I will not argue against having a map and compass if you will be spending much time in the forest off the trail, or even to have as in-camp reading material, looking ahead, looking back. If you don't want the weight, and won't be using it for daily navigation, I would suggest using Phil Endecott's Topo Maps app. The GPS works on airplane mode, too.
