First, it will be easier for some of us if your weights for individual items are in ounces, not fractions of a pound. Also, separate your worn items (or items always in your hands, like hiking poles) from your packed items. Packed items=base weight. Having said that, here's my two cents:
Ditto what the post above says: your big three are too heavy, mostly the pack and tent. You seem to like Osprey–their Exos and Hornet series are much lighter than the Atmos. Cottage gear makers and/or going to a frameless pack will be lighter still. You use poles, so get a shelter that uses them instead of tent poles and save some weight. My shaped tarp and groundsheet weigh less than a pound, for example.
There's a lot of redundancy in your list. No need for 4 pairs of socks, for example, or a pack cover (which won't work as well as a liner in any event) AND a 10 liter dry bag. No need for water shoes with trail runners–just wade thru and keep going. Or two knives, esp. the SAK at over 4 oz.
Once you replace the tent and pack, and leave a lot of stuff behind, you can start trimming the weight of the smaller stuff. Getting to 10# or less base weight isn't too hard. Mike C!'s book (linked above) is a great resource, as is looking at the gear list of others on this site (click on the screen name over the avatar pic to go to the user's profile–many of us post lists there).
Good luck–I'd love to do the PCT someday.
