I agree with most of the comments -- you don't need that much food and you should chuck the stove. For an overnight in mild weather I don't bother to cook -- why bring a stove if you don't need it?. In fact some pita bread, cheese, hard salami, apples, and a couple of peanut butter sandwiches and some trail mix fruit bars would be more than enough. Some hard candies are good to have to suck on while you hike -- helps keep the thirst down.
And you only need one change of clothes and maybe an extra pair of sox, a fleece jacket for warmth and a rain jacket and pants, plus a broad brimmed hat to protect against strong sun or falling rain. One major item missing is a tent or bivouac bag. The mosquitos are biting this time of year and there is also a strong chance of rain -- what are you planning to sleep under for shelter? Weather can turn really nasty quickly up there. Do you have a reservation at either of the two shelters? There are only accommodations for less than 20 people total and no camping is allowed except at those locations. See this link on the area restrictions.

You don't mention sanitary items either -- you need a plastic trowel to dig a toilet hole, toilet tissue and a small bottle of waterless hand cleaner. Far as I know there are no porto-sans on the hike. A basic first aid kit with bandaids, tweezers, alcohol wipes and something for insect bites would be a good idea. Oh, and sunglasses and a watch (so you can keep track of your pace and get back down to the camping area before dark.)
You should have a sturdy internal frame medium sized backpack to carry this in. Try to keep your total load under 20 lbs. A water filter is a good idea and will save weight, but don't count on there being sources at regular intervals -- check on that with the park service before you start. The biggest concern in that area for water contamination is Giardia (carried by humans and beavers) -- I believe both the Brita and Pur portable bottle filters remove that and cryptosporidium. They are reasonably priced at discount and drug stores.
And you probably will want to take a camera. The White Mountain scenery is well worth remembering!
