Ditch the tent, you should be able to save 3-4 lbs easily. I use a Tarptent Cloudburst 2. Sleeps 2, but has lots of room for 1 and weight is a little over 2 lbs. After that, just minor things:

1) forget the spare batteries. Put fresh batteries in everything. You can always find a store with batteries along the way.

2) Is that Ipod a new one with built in camera? If so, you could forget the camera.

3) Ditch the Camp Lantern, you have the mini headlamp to provide light

4)Alcohol (for the stove) - do some test to determine qty required to boil a cup of water, then multiply by # of meals you'll be cooking. Don't just fill that saline bottle full of alcohol, that's a waste of weight for a short trip. Also I found that the bottles from gasoline stabilizer work better since they have graduations on them. That helps in dispensing the correct amount of alcohol.
