Just a few comments, remember you asked
I would take another look at you cook kit. Unless you are planning to do gourmet cooking, I would suggest getting rid of the bowl and cup. 1 pot is all you need. Unless your girlfriend is going to use the bowl, then just dump the cup.
Looks like you need another water bottle to me. Smart water or Gatorade.
Fabricate a heat shield for your pocket rocket, make sure it is well vented at the bottom to keep the canister from overheating. Aluminum flashing from the Home Depot works well for this and the weight will be mare than offset by the fuel you will save when its windy.
No need for a pack towel and a bandanna.
You might want a small thing of sunscreen. I don't know how easy you burn, but it's something that is easy to dump in a hikerbox if you find you never need it, but if you get sunburn, you will be miserable for a few days. Might be worth the 2oz.
Are you ever planning to hang you food? I didn't see any line? (never mind, just saw where you are planning to take paracord)
Crocs are pretty heavy for what they offer, and they are dangerous on river crossings (IMHO) because your feet slip around in them.
I don't see a compass, if you feel you don't need one, just make sure you have a compass app on your phone. There are times when knowing where north is can keep you from doing stupid things.
I don't see rain pants, even if you don't hike in them, they are great to have in camp on cold wet windy days.
You might want some type of ground cloth for when you stay in shelters. Shelters are pits, and the ground cloth helps keep your gear clean and helps to keep your pad from popping a leak from a splinter from the shelter floor. It also makes a good sit pad when folded up (when everything in sight is wet and muddy).
One last thing, and I know you didn't ask, but I highly recommend you don't divide the gear in a way that makes your girlfriend totally dependent on you. For both safety and sanity, she needs to be able to hike independent of you. It can be unnecessarily stressful and possibly dangerous to be put in a situation where your safety and well being is totally dependent on someone else. She needs the freedom to be safe warm and dry when she is not with you. She may end up carrying more weight, but she will thank you in the long run.
