The Osprey Atmos is a more popular backpack than that Volt. Fit is really the most important part of this - so if you have a chance to try either on - that would be ideal.
These poles are better than the ones you have listed:
The North Face Venture jacket is more popular / recommended than the Resolve:
Skip the solar charger. A USB battery pack is way more useful. Solar are just too bulky and low charge for the effort. Get 2 if you really need the power.
Tent is really small and not a popular/quality brand. How much time will you spend sleeping in this? Every night? Have you ever slept in a 1-person bivy style shelter before? Where will your backpack go at night? I would not recommend this. If you really need to go this cheap (under $100 is SUPER low for a quality ultralight backpacking tent) - then consider Nature Hike brand. They are a knockoff Chineese company that's somewhat good.
That sleeping bag is garbage. It's super bulky and not very warm. The 32F rating is a straight up lie.
I recommend this bag instead:
You also need a sleeping pad. Not optional. Check this out:
100% skip that hammer multitool. WOW is that thing bad. If you need a knife - buy a knife. You do not need a hammer for backpacking.
The headlamp is great, good choice.
The stove / pot / cook kit is okay. It's a popular budget option. If you could spend a bit more there are better choices. For example:
Don't forget TP/wipes (and a way to pack them out once used), good wool socks, dry bags / pack cover, food bag, water bottles, map, first aid, toiletries, lighter, duct tape, phone/camera, and other random items. Plus clothes of course - lots of layers!
As a big side sleeper, I found this remarkably comfortable. It's not self-inflating, but takes less than a minute to blow up. Although it's thin I've never bottomed out: the V shape does an excellent job of support. It's the best camping pad/mattress I've ever used, including ones that are much thicker. I know it's not exactly what you're looking for, but I thought I'd throw it out there.
