Welcome aboard! You've got a great list. Here are my suggestions:
Emergency Bars (Datrex) (two packs)
Emergency Water (six 1 pint packs)
I started by defining a reasonable emergency for which I had to prepare, and my definition was "spending three days stranded in a snow bank." Based on that, I carry more food and more water than you do.
If you haven't tried them, I found that Mainstay bars taste better to me and my family than the Datrex bars, but whichever one works for you is good. You can save money on the mylar pouches of water -- what I do is put a case of bottled water in my trunk and replace it with a full case when it gets down to about half-full.
Emergency Blanket (Silver/WaterProof)
Consider replacing this with a Heatsheet. The straight mylar ones are very delicate and can easily tear in use.
Dyno Flashlight - (Emergency Cell phone charger)
There are crummy versions of this that don't use a capacitor. Instead they have a coin cell or two. After a year or two, the coin cell dies and the light no longer takes a charge. Many of them will stop working permanently at that point.
If you have a good one that's capacitor-based, awesome.
My personal experience with this is that I've used it four times and never had it actually work to seal the flat enough to let me get back on the road.
Your flashlight should be an LED. Compared to incandescent bulbs, LEDs are far less susceptible to shock, have better battery life at any given light output, and the emitter never needs replacing. You should supplement your flashlight with a headlamp.
If you're using primary (non-rechargeable) batteries, use lithium. They provide a lot more energy, especially for high-drain devices, last much longer in storage, and don't leak.
I carry one per person who might be in my car.
Water Purification Tablets
Make sure you have a container to disinfect (not purify!) the water in.
