Packing my bags, I'm ready to go

Luggage to be checked- packed and maxed out ay 50#'s. Another 50#'s in carry on and personal item(backpack) that I get to lug around the airport. And still I contemplate...what might I need that I have forgotten to pack?
I will be there for a month so I have packed with laundry services in mind and the end goal to leave an entire suitcase full of belongings to be donated.
So here's my list:
Workboots, flip flops, sandals and tennis shoes. (socks)
Workshirts, dress shirts (some will do double duty).
Shorts and "pants".
Skirts and dresses for dinner and sightseeing.
Work hats to keep the sun off my face- sunscreen and bug spray.
Pj's, robe, unmentionables, swimsuit for Lake Sevan.
Treats, supplemental foods to get me through breakfast at least my first day before I get to the store.
Work gloves, duct tape(in checked bag), paint rollers, and brushes
Gifts for my friends in Armenia.
First aid kit for the team, personal first aid items.
Bathroom kit plus my Qt ziplock wet bag for carry on.
Mini computer, iPod, speaker- cordage.
Team paperwork etc, reading material for the flight,Armenian  translation dictionary.
Vitamins, medicines, make up.
(Hipscarf to practice my  dancing during free time, and perhaps a little show for my friends.)
Photo printer, ink and photo pages- cordage, et.all, as we will create a scrapbook for our host family which I will be working with for the entire month.
Passport, eTicket(in 2 weeks), Cash because credit/debit doesn't go over so well there.


I feel like I am missing something. I may or may not be. It seems like I have an awful lot packed already. I know I will be able to buy certain things there, but still in my desire to be self sufficient I want to be prepared.

I am ready with 2+ weeks to departure. But being ready already now I have to wait. In my waiting will I try to add items to my already burgeoning bags, which will be a burden in the traveling? Each year I try to squeeze the maximum load into my suitcases only to arrive and have items I never wear/use the entire time. The good news is that I am leaving most of it in Armenia one way or another!
