Wow. Any estimate on what that load would weigh? I'd be surprised if it came in under 100 lbs.
I guess I come from more of a backpacking background. Pack light and move fast are keywords. My personal preference would be a good internal frame pack vs. all the over the shoulder and belt gear. I'd also go with a bladder instead of multiple water bottles. From your food list, your mess kit is probably unecessary. I'd go with a small titanium pot, a plastic cup and a plastic bowl. I'd also go with a light sleeping bag vs. multiple blankets. As mentioned, spare clothes can sub for the pillow, though we seldom carry much in the way of spare clothes. Just fleece layers and wind/rain shell.
Binoculars and cameras are fun, but not essential. I'd also look really closely at the heavy tools on your list. There are lighter knives than the Buck 110, too, as nice as it is.
It's all a matter of what you're comfortable with. You might want to start putting each bit of your kit on a scale and asking yourself, "Do I really need to carry this?"
