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.
