Yikes!
Good job!
Sounds like the only thing you are missing is paragraphs!
I also have a fair amount of food in mylar bags, either in 5 gal pails or in boxes, some bulk, and some in smaller amounts, like oatmeal 2 lb 10oz, in one bag so I don't have to open up 20lb tub, but something that is missing is water.
I don't think many folks consider how much water we need. Drinking, cooking, cleaning, and hygiene. If there ends up being a SHTF event, then staying healthy is going to be paramount. You can live for a few days without water before you die, but dirty water is not much better, you will get sick and die as well. Sanitation is one key element to staying healthy. So you will need water for cooking, and drinking, clean sanitary water for cleaning dishware...., the amount of water you will need is more than most think.
Look for your water sources, ponds, streams, rivers, lakes, rain-barrels, pools.
I don't believe that just a ceramic filter system is adequate, the system does not produce enough water, and will get clogged pretty rapidly if water is very dirty and full of particulate matter.
I have developed a system that uses 4- 5 gal buckets one with a 100-50 micron filter, next 50-20, next 2ea 20-5, and last 2 ceramic filters. The last 2 are the slowest, keeping buckets full helps keeps pressure up and better flow.
My procedure is first filter water with cheesecloth through funnel, let water settle to remove heavy stuff, then pour into 5 gal bucket, I have a fixture at the bottom made out of a PVC cap with holes drilled in it, I put more gauze and filter water one more time, then it gets poured into each bucket with filter progressively getting cleaner.
For basic hygiene the 5 micron water is fine, for drinking use ceramics which get down to 99.5(but take longer to filter). If you have buckets set up for all containers this is a continuous process, final water still should be treated with chlorine of some type household bleach, calcium hypoclorite, or UV(found a 12 volt unit).
Last point you will need something larger than 5 gal buckets to store water, you can use bathtub in short term, but 55 gal food grade barrels probably best. my 2 cents
