I've put some thought into this, as I live in the country and have wondered how I'd go about things in a SHTF scenario.

Acquire a steady supply of water -- I've got a well. That's great compared to someone who depends on the city for water. The problem being, if the power does go out, my well (with all of its water) just sits there waiting for me to pull the water out. I could get a generator to power my well pump, but eventually I'll run out of gas. So I've got to figure out another way to convert my current well system into a manual pump system so I have a steady supply of water that isn't dependent on electricity.

Then, a variety of nutrition is needed.
Gardens are great...I have one every year. Canning works to have your veggies last much longer than fresh, and doesn't really require refrigeration. But the flavoring can be off-putting after a while of eating canned goods. So you want frozen. Well, that requires refrigeration.
Again, unless you have a generator, you're going to need some sort of power source to work refrigeration. You can sort-of fake it with a root cellar, but that's still not cold enough for true refrigeration in areas. So you need some sort of passive power generation. Solar, Wind, or Geothermal are possibilities. Expensive to do, but if you can figure out a way to collect power in a less expensive manner, you can use it for refrigeration. Then you can do frozen goods as well as dried and canned goods.

Then you need meat.
We have chickens, which gives us eggs and can give us meat in extreme emergencies. But without a semi-regular supply of meat, you're going to experience some malnutrition in a diet (during the long-run) consisting of only garden veggies. So you either need to figure out how/where to hunt, or you need to acquire animals to provide you with food and continuance.

1 cow can be good. It can provide milk, but requires a fair bit of feed. The cow also provides good fertilizer for your garden. But once you eat it for meat, your done with it. No more milk, no more fertilizer.
So you need 2 cows (male and female) that can give you a new cow each year. The new cow can provide the meat, while the 2 cows provide milk and manure for your garden.
Goats can also substitute for cows, but obviously the quantity of meat changes.

Finally, you need a hobby suitable for the SHTF scenario. Learn to sew/mend clothes. Collect data for storage purposes. Learn to reload bullets. Learn to blacksmith. Learn to build things with wood using hand tools. Learn leather crafting. Things are going to wear out, so they're going to need replacing. If you get a hobby that can produce new material that is useful, it'll help out you and your friends, and could conceivably be used for barter for things in other towns (assuming money becomes worthless).

That's about all I've got.
