Jared, for your first shot this list is really good, here are my comments:
MSR Bivy 9 oz. =you could cut a few oz's here but good for now
Ground sheet w/stakes and
stuff sack 10 oz. =this seems heavy, you don't need a ground cloth when using a bivy and it probably takes up half of this weight, also loose the stuff sack, use a rubber band or your stocking cap to keep them together
1 stuff sack for bag 2 oz. =stuff the bag into the pack liner without the stuff sack, this is great in the bottom of the pack.
Platyous 1 liter bag w/
sawyer inline filter 5 oz =you are carrying tablets so you could loose 5 oz's here
Thermarest Z rest (cut) 8 oz. =hope you are comfortable with this
Pocket Rocket 3 oz =for short trips you could use a pop can stove
Snow Peak pot, spork, and
lid 6 oz =maybe loose the lid and use foil
Total 9 oz
GoLite Phantasm jacket 9 oz =you could go with a poncho tarp and loose the jacket completely
BD trekking poles 17 oz =a little on the heavy side
First aid kit includes teepee, water tablets 13 oz =this is where you can save a lot of weight. first aid could be 2.5 oz, loose the teepee or just take only what is needed. What else are you trying to survive? Maybe add some fire starter (tinder) and sunscreen (repackaged).
Lighter 2 oz =is this a zippo? mini bic is 0.4oz
Gerber 3 inch knife 2.7 oz =Swiss army classic is 0.7 oz or a safety razor blade is close to 0.1 oz
Compass and map 4 oz =1 oz compass, 3 oz map- a green trails map laminated is only 0.9 oz, one or the other is way to heavy
Hope this helps, I had to do this quickly, wish I could have spent more time.
