Lots of small light stuff, still makes for a heavy pack. Besides this list is pretty much useless to critique without weights for these items, your location, planned trip length and expected temps.

For three-season only (I am ignoring winter gear)

-Nix either the pants or shorts-- or purchase a pair of convertibles.
-There is a world of different between a fleece and a synthetic jacket. Nix the the former, take the latter.
-Nix one T-shirt. One T-shirt and mid-weight top is enough for most 3-season use.

-Nix the heavy waterproof boots-- look into non-waterproof or trail runners. They are lighter and dry quicker. Your feet WILL get wet regardless. I would rather my shoes dry in overnight, than in 3-4 days.

- Nix one pair of socks. Two pair is fine (wear one, sleep in one).
- Liner socks, one pair is enough and depending on your location may not be necessary for three-season use.

-Go with an internal frame pack

-4 season sleeping bag is going to be heavy and too warm in the summer. Consider purchasing another bag for summer and warmer conditions.

- Same applies to your tent.

- Which sleeping pad. The is a world of difference between a Z-rest and winter pad.

- White gas is overkill in three-seasons
-Cook set-- what does this include?
-Spork, bowl etc-- isn't this part of your cookset?

-Nix the extra batteries for headlamp. Use fresh ones at start of trip.

-PBL, nix
-TP nix
-Trowel nix-- use a rock or stick.
-Pee bottle, serious, nix
-Cariberner-- what do you use these for? Nix if possible.
-Firestrike, lighter and matches? Nix one.

-What is the extra paracord for? Nix if possible.

-FAK, what is in here?

-Nix signal mirror
-Nix emergency tent/shelter
-Nix intinery-- memorize it-- it is YOUR trip. you should know it by heart.

-Bear spray-- not need IMHO
-Repair kit, what does this consist of?


I don't see:
- Hand/Clothes soap
- DEET

Since the lack of specifics-- something tells me that you do not actually have your gear yet.
