Ditto on #5 above. I also recommend low-cut socks for two of your three pairs. The super low cuts are too low for me, but the styles that just reach the ankles are my favorites. Less sock means they dry out faster. I have a regular length sock for camp. I have a couple of large locking safety pins (made for diapers) to hang wet clothes off my pack. Smaller pins work, too.
For hiking poles I have used both Leki Ultra Lights and the Gossamer Gear fixed Light poles. You might not notice any difference unless you are holding one of each. The Leki poles feel heavy! Over a thousand miles, swinging the lightest pole might make a difference. Both are strong. Both companies replace broken poles fast. The Leki tips fit on the Gossamer Gear poles, so replacement parts are available from outfitters along the trail. The continually shock of poles striking the ground can cause "tennis elbow", so keep that in mind if you start to develop forearm or elbow pain. I did break a pole once, but quickly adapted to using just one.
Although I do eat out of the cooking pot, carrying another container can be useful. You can have a bowl of soup cooling as you are cooking dinner. I like flexible bowls like the Guyot Squishy Bowl and the Orikaso Folding bowls. The Squishy can be folded inside out for easy cleaning, the Orikasos can be lain flat so are easy to clean and store in your pack. When a water source is very low in the summer, like a small puddle, flexible bowls make it easy to scoop up the water. Sea to Summit makes flexible bowls, the "X bowl". Snow Peak makes a solid lightweight titanium bowl.
Once you decide on the volume pack you want, go for the lightest model. The more weight you shed, the better. A frame pack means sore shoulders and sore hips. Frameless packs means only sore shoulders. You just have to weigh (no pun intended) the advantages of both and decide. Remember, however, if you load up your pack with ten days worth of food, you only have to carry that extra weight for one day! I agree that Osprey packs are popular. One model has a ridged mesh pocket holding the pack off your back. A hiker carried his water bottle in it. The pack was large in volume, yet compact. Outfitters I've visited along the trail ( in GA, NC, VA, Harpers Ferry, PA, NY, MA, NH, ME) all carry Granite Gear models. Apologies from a gear nut!
