I made some notes. You should formalize your list a little more. I foresee you adding things and not being super accurate. The spreadsheet list is an amazing way to quantify your gear.
For instance, you have no SOAP but you list 4 ounces of Toilet Paper. And 4 ounces of TP is a LOT.
Also - you list a "Misc. Nalgene 6.20 oz" and I am not sure what you mean. Make sure you have a very real NEED for any item listed.
For water vessels, You listed:
Misc. 3L Platypus Hoser 4.00
Misc. MSR Dromlite 6L 5.70
Misc. Nalgene 6.20
That's 10 liters of water!
And they weight 17.9 ounces empty. A 1.5 liter soda bottle weighs less than 2 ounces (and it's free!) You save OVER a pound.
And if you are in the "colorado rocky mountains" you can get by with less than 2 liters.
Backpack Osprey Exos 58 40.00 - WOW, that's too HEAVY. Start by getting a lighter pack.

Misc. Nalgene 6.20 - What?!?!? More water bottles? Just so you know, it is the "traditional" hiker that carries the Nalgene bottle, NOT the light weight hiker, NIX it.
Misc. Petzl Tikka Plus 3.20 - Get a petzl e+lite, it is less than one ounce.
