Thanks for your replies, everyone. I'll elaborate a little more:
My total pack weight came out to 18.7 lbs. I knew the weight of my tent and my sleeping bag. Just about everything else was estimated to fit in the total weight, so for all I know, I could be way off on some of the weights I listed, like the spork.
The "survival kit" is composed of a small first-aid kit (bandages, two single-packs of Advil, some anti-bacterial cream for cuts, etc.), a small flashlight (about the size of a small pen), batteries for the flashlight, an emergency blanket, a rain poncho (I forgot there was one of these in there, I don't need two), a whistle/compass/waterproof match container, waterproof matches, a lighter, and a very basic Swiss-army knife.
I'm guessing I should remove the Swiss-army knife, the poncho, and the flashlight.
The camp axe - I've never cut down a standing tree. I only take what I need from fallen trees. I've never built a fire pit from scratch either, I always pick a site that has a pre-existing one. I don't like folding camp saws - I've broken several.
I've cut just about every strap on my pack and on the compression sack that came with my sleeping bag. I don't know how much weight it took off, but it had to be at least a couple ounces.
For my tent, I'm looking into lighter stakes. I don't know if there are lighter poles available or not.
As for a stove, two of my friends had MSR Pocket Rocket stoves to use, so I was covered there. For food I brought Kraft Easy Mac and a Bumble Bee Chicken Fillet, which was surprisingly pretty tasty. I also brought some trail mix and a few small chunks of Parmesan cheese. Breakfast was a Rice-Kripsy treat to hold me over until we went to a diner after leaving the trail.
My pack is packed like this:
The sleeping pad lines the sides of the pack. The tent bag and sleeping bag go in the middle and take up the rest of the available room. Everything else goes on top of the sleeping bag, which is about half as high as the tent bag. I close up the main part of the pack using it’s drawstring. In the top pouch, which goes over the main pack section, I put my poncho, my spork, the map, and the headlight. The axe goes on the side of the pack, the head resting in one of the side pockets, and the handle cinched down to prevent the axe from moving around. On the other side, two 20 oz. water bottles took up residence, the rest of my water being carried in a 2-liter hydration bladder.
I don't mind getting my list torn to shreds - it's what I'm here for :-)
