You're counting water in your base weight? Clearly a consumable. There, you're below 8 lbs.
That said, you have a great gear list except for the camp shoes. You have camp shoes already, two in fact: bare feet and your hiking shoes unlaced.
Also, no toilet paper. Mike C: http://www.youtube.com/watch?v=zwmwxkD86Ec
I like a sit pad, but I only bring it when it will be used in cold weather as part of my sleep system. Otherwise, dirt is fine.
It wasn't in your base weight (I think) but do you bring the binocs? Again, a luxury item, and luxury items are why it's great to go UL, but do they really make a big enough improvement to justify the weight?
I like a headlamp, since I'm often up after dark, even in summer, but that means I burn daylight sleeping in. But if you won't be up, a simple light for a run to the tree at 1am is good enough.
I'm not big on commenting on gear lists, but the water included struck me as odd. Yeah it weighs something and you will definitely feel 3L of water versus 0L, but we're talking base weight here, right?
Hope this helps the decision.
