Looks like you covered all the bases.
At a glance, my suggestions:
-Ditch the camelbak pack, just stick the bladder in your Deuter for hiking.
-You only need one canister of fuel unless you're doing all the cooking for 3 or more people. I can make a 4 oz canister last 20 or more meals if you're just boiling water.
-get an aluminum bubble-wrap windshield sunshade at the auto parts store and make a cozy for what ever you eat out of, pot or ziplock. It reduces fuel needs by 'coast cooking' and you won't burn yourself either.
-Ditch the surefire. your headlamp is plenty of light for around camp.
-I'd swap the knife for a swiss army esquire (scissors) but if big knives are your thing, I know how people get without them. I hike with a buddy who carries THREE. I personally cut dozens of moleskin, tape and string pieces with scissors and rarely even open the knife blade.
-Ditch the blue poly tarp. It's bulky and heavy. good site selection and prep eliminates the need for a ground cloth. If you need a clean place to stand in front of your tent, take a trash bag and lay it down. If you feel you MUST have a groundcloth, get painter drop plastic and cut it down, or google shrink-wrap window insulation. It's much more durable than it looks.
Swap the cotton hoodie for fleece, or if you can swing it, a synthetic puffy. Many reasons for this. better warmth to weight ratio, and nicer to sleep in if need-be.
Get a topo map to supplement the GPS. Trust me.
For your future list:
You can get some really decent trekking poles at K-Mart, WalMart, Big 5, Sports Authority, Dicks, or Costco for under $30 a pair. No need to spend a Benjamin on Name Brand. I personally have a pair from Costco that cost $28 and are still rock solid despite me beating the p!$s out of them for the last 6 months climbing 14'ers.
A decent compass is $10-15 at any Big 5 or similar. Brunton makes a good one.
Good luck and enjoy the trip! Don't get too hung up on gear. go have fun.
