looking over the list, i would agree that it is clothes heavy. that list is based on the packing list for Philmont.
Clothes when I go, I usually wear cargo pants and a long sleeve shirt, even in the summer, but I am odd. Then I take at least 1 extra pair of skivvies, maybe more depending on how long I am going to be out. Not more than 2 extra because you can wash your clothes, so you wear one, wash one, and have a dry one. I almost always take a fleece and in the winter or in the mountains I take my beenie and gloves. I've seen a nice hot summer day turn into a cold summer evening when a storm hits and socks just do not keep my hands warm. So I don't think it is too much warm clothes, though long johns are certainly not something everyone needs.
Socks, I do not use liners, just wear cotton socks. Entirely up to the individual.
Sleep clothes is just as ccard said. We had to use them at Philmont because of ursusguy.
As ccard said, a lot of it is personal preference. If you have a means of staying dry and warm, you will be fine.
If you look in my pack when I head out, it is typically full of books. I love to read on the trail!
As far as stoves, I think the fuel rule is a good guide for canister stoves as well. I haven't used one since I was a kid (I use a WhisperLite) but I compared the pocketrocket and the whisperlite. Both have similar boil times. The PocketRocket will give you 150 min on 20 oz, the WhisperLite will give you 136 min.
And then a personal little sidenote for me. I wear cotton and I love it. Cotton doesn't kill like everyone says. Hypothermia can kill. Burns from a stove can kill. Falling off a cliff because you were trying to look cool in your new North Face polyester shirt can kill. They say cotton kills because it doesn't dry as fast as synthetics when it is wet and doesn't stay warm like wool when wet. But you know what I do when the possibility of rain occurs? I put on my rain jacket. You know what I do when I get wet in a stream and start to get cold? I put on dry clothes. Now earlier I mentioned burns from a stove. Let's say you get into camp at 7PM, starting to get dark and you are starved. You fire up your stove, get your trail meal #11 out, put your pot on the stove and turn to look for your water bottle. There it is, on the other side of the stove. You reach across and in your tired state, you accidentally hit the pot. You instinctively reach out to stabilize it and you catch on fire. Oh my! You arm is on fire! And now that polyblend shirt that looked oh so cool hanging on the rack at REI is now melted to your arm! You are so uncool now. Cotton doesn't melt like polyester when it burns.
And now for everyones enjoyment, a pic of Pro Sandy on Echo Peak in his awesome cargo pants, button up green shirt, and cool yellow fleece!
