The problem I see with your kit is that your safety margin is WAY too high and therefore your kit is heavy. Obviously, there is a lot of gear where you can go lighter but this will take time and $$$.
Osprey Atmos 65 pack - This is a lot of pack. You can save a lot of weight here. Look for something around 26 oz or under. Check out Gossamer Gear packs.
Feathered friends sleeping bag 20 degree as it can drop into the mid 20's even in August - This is fine. I'm not familiar with this bag but FF makes good light bags.
Big agnos copper spur UL1 tent, stakes and rain fly - I'm not familiar with this tent, but having an additional rain fly makes me suspicious that it is too heavy.
REI Stratus sleeping pad - There are much lighter (e.g. NeoAir). You can easily cut this weight in half or more.
MSR miniworks water filter - Again, much lighter options such as Steripen, Sawyer Squeeze, tablet (blech). I always carry a backup.
GSI pinnacle dualist cookset - Look at alcohol and esbit stoves such as what you might find at traildesigns.com. I have a JetBoil Sol Ti which, while not UL, is a great compromise.
Nalgene canteen collapsible - too heavy. I use Smart Water bottles and platypus bottle (for camp)
small bag of toiletries (sunscreen, deet, chapstick) - watch this stuff as the weight can add up. Put small amounts of sunscreen, lotions, Dr. Broners (which doubles as toothpaste) in tiny squeeze bottles. Dity bags conceal a lot of weight that can be minimized.
small bag of firestarting materials (lighter, tinder, matches) - mini bic and some cottonballs dipped in Vaseline
Lightweight Northface rain gear (jacket and pants) - Personally, I haven't found NorthFace gear to be very light. Though my information may be outdated.
Mid layer ultralight Northface jacket - layering is good. For this layer you are looking for a target weight under 8oz.
Two pairs of wool socks - 1 extra pair
One extra shirt, pants, underwear - drop the extra pants, though I carry extra shorts.
First aid kit - keep this down to the bare minimum. Most first aid kits are overkill. This is a very subjective subject.
Compass - will you be off trail? Is the trail system Byzantine? Otherwise drop it. If you MUST have a compass get something very light.
Leatherman wave - drop it. See knife.
Mora Knife - Mora are great knives but what are your plans for knife? building a shelter? fishing? batoning wood? I would say that most people use knives to cut cord, food packaging, etc. A Swiss Army classic is a staple of the UL backpacker though there are many other options.
Black Diamond spot headlamp - heavy. Unless you are going to be hiking at night, go with a small photon light.
Two carabiners - 1 mini light carabiner for your food bag
25ft of paracord (mandatory) - 50ft of spectra cord.
Stuff sack containing 9 lbs of food - 9ft sounds right, though you could probably get this to 8 for 4 days.
Glock 40 in a hip holster - For Bears - not enough gun. Pepper spray.
