Clay good start- I hope the sub kilo works out- here are a couple of my thoughts on how you might shave some weight and save a lot of money in the long run.
No need unless you use it for a swimming suit
>Under Armour synthetic TS<
No need you are already wearing one and you have the wool base layer below
>North Face Fleece< If you haven't bought this already there are much lighter options for the same cost- Montbell down inner jacket 6.9 oz. You can get one off gear swap.
>Omni-wool base layer top
Omni-wool base layer bottom<
I would just wear these and not have any of the Under Armour, leave all the UA at home and if you haven't bought the columbia shirt yet- get the BPL Thorofare instead!
>4 Dry Sacks<
Ditto on the compactor bag, maybe a drybag for hanging, but you can make a silnylon stuff sack for cheap, and it is lighter.
>Big Agnes insulated AirCore Pad<
This is a heavy pad! You are better off with their lighter un-insulated version (Clear View). When necessary carry a thin closed cell pad, this would be lighter and better.

>Nalgene widemouth canteen 1L<
These things weigh 4 to 5 oz's, go with a gatorade bottle they are 1.7 oz. and are free!
When full you are carrying 6.52 pounds of water- If you are hiking in the desert you might need that much at a time but I bet water is more plentiful in WV. Use an old gatorade bottle or 2, it is way cheaper and easier to deal with.
>Snowpeak gigapower stove
Snowpeak 110g canister<
for short trips I would save the money and MYOG Alcohol stove. Or get the Caldera cone for your MSR Kettle.
>Adventure Medical Ultralight .9 first aid<
Make you own up, again far lighter and cheaper. Jason Klass has a video that might help.
Hope this is helpful.
