Looks pretty good to me.
A question about your socks: do you intend on using the same socks every day? I don't use socks, personally, on the trail when it's above freezing; but, from watching those who do, it seems that having more than one pair so that you can have at least semi-dry feet is a good idea. Or does that weight total include two pairs of liners and outers?
Sleeping socks: I see in your winter clothing that you don't have any listed. I find that, below freezing, it's worth having a pair of thick, loose wool or acrylic socks to keep my toes warm. YMMV here, but I find it worth it.
Your hat: would it be worth going over to a visor/bandanna combo? A $1 WallyWorld cotton bandanna (I didn't see any listed) is about an ounce, while my $8 Rothco visor weighs about 2.5 oz. You get the multi-use of the bandanna (sweat rag, sun protection with the visor ala the Foreign Legion, water pre-filter, emergency splinting material, tarp wiper-offer, etc.), better ventilation for your head when you're not in the sun, the same weather protection for your face, and it comes out about an ounce less than your current hat--all for under $10. Just a thought.
Why is the Sawyer filter listed at 8 oz? Mine is ~3 oz wet, ~2 oz dry. Are you including the backflush faucet kit in that weight?
I'd add a button compass to your tools. You're going to be on the AT, so it's unlikely that you'll get lost; however, having a tiny ~1/2 oz button compass to make sure you're headed in the right direction might be useful, especially after a long tiring day.
Otherwise, everything looks really good. Assuming that you're careful with your gear (the tulle bugsock worries me a bit, but I'm hard on gear), you should be good to go! I hope the hike works out for you!
