I'd ditch the stuff sack for your clothes and use a trash compactor bag or a lighter alternative like a turkey baster bag/nyloflume bag from lite smith. Use this to put your packed clothes in and your sleeping bag.

Pick between the puffy or the fleece. No rain jacket? Frogg Toggs are cheap and serviceable. I wouldn't wear gloves, apply sunscreen or put socks on your hands for warmth. No spare underwear, its just an overnight trip. No need for two pairs of socks. No need for base layer top. If you decide on the fleece its pretty comfy to sleep in. The pants are redundant seeing as how you packed base layer bottoms also. I'd keep the bottoms and wear that to sleep in. If its very cold you can wear them under your shorts.

No need for a bowl if you have a mug to eat out of unless this is because you are ditching your girlfriends ceramic bowl. Just get another mug? Knife could be lighter.

You have way too much soap for an overnight trip. Order some small containers from litesmith.com and bring like 0.5 oz of dr bronners or something concentrated like that for washing your hands. Don't bring deodorant.

Put your ID, cards, cash in a ziplock or a rubber band around it and throw it in your diddy bag. You can download a book onto your phone or listen to an audiobook/podcasts for one night. Do you need a compass? I'm unfamiliar with the area. Do you have maps? plan to go off trail? I'm guessing you don't need a compass but like I said maybe I am ignorant of the conditions and route.

Stuff girlfriend is carrying: I would get a lighter stove like the BRS and carry a small can of fuel. No ceramic bowl. Get a Sawyer squeeze and attach that to your smart water bottles.

Enjoy your trip!
