WOW !!! Well, for what it is worth I agree with STORM. Learn the skills that are needed for a self- sufficent life as you go. Don't try to do it all at once.
Add to your food stores steady, and just extra of what you use now. There is no sense in going out and buying a years supply of freeze dried food for every member of the family, only to find out that one of them does not like something on the list, and will probably not eat it. Stick to what you like, and buy in bulk when possible.
Extra ammo is a given thing when you own firearms. Lots of debate over how many rounds that you should have for each gun. I can not tell someone that they should have X number of rounds of ammo for this gun or that gun, but I do have a few thoughts that I will share with you.
The .22 cal. is a round that can't be reloaded. They are cheap. So as a tactical thought, buy as many of these as you can get. If you end up with 50,000 rounds, and you might end up only using half of that in your lifetime, think of the other half as trade and barter goods to be used for something that you may find later that someone has, that they might trade for say maybe a brick of .22's .

The 7.62 x 39 is a good one. Like the .22, stock up as you can afford it. It can be reloaded, but because it is a rifle, there a few things that go along with the reloading of it as opposed to a hand gun, that need to be addressed. Learning to reload you own ammo is a good skill to learn as well.
The chance of you getting into a firefight with hostile forces is small, but if it were to happen, the amount of ammo that you might use would be a shock for sure, and unless you are able to resupply like the military, get a lot, and get some more. If you never need it for a fight, you still have a good supply of barter goods / box . And if the current presidential administration holds true to form, they will be quite literally, worth their weight in gold. 5- 10,000 rounds has been suggested for all rifles. Some people think that this is a bit much. Maybe.....maybe not. You are the one who will have to decide this debate.
Pistol rounds are close quarter rounds. You may not need as many as a rifle, bu these need to be stockpiled as well. Shot shells are the same.These can be used as food gathering rounds as well as defense rounds. Get what you might need, and get some more of both. and when you have them, get some more.

As building projects go, do what you can, as you can do it. If you are going to can foods that you grow and produce, build a good root cellar. Raise chickens ? Build a good chicken coop, as well as an enclosed run to protect them from predators. Need more storage ? Build another utility barn. Need an extra home on the old family homestead ? A good log home with a wood stove, and a good well or cistern for water storage is a good thing. Also, on the subject of off -grid power, the government will be giving tax breaks on new instalations in 2009. Worth checking out if you want to decrease your electric energy dependence.

I have given my two cents worth, and you can take this all for what it is worth. Before I go, a few last thoughts are in order. If nobody in your home is a doctor or nurse, get some basic, as well as some advanced first responder training in first aid. Accidents happen, and it may take the emergency services people quite some time to get to you in an emergency. Seconds count, so be ready to render first aid until they get there.
Since you have firearms, a good training course would be a good thing to go to. Since you have an SKS, a good thing for you there might be to go to the Suarez International site and get his training video on the KALASKNIKOV family of rifles.
http://www.suarezinternationalstore.com/You have a leg up on where most other folks that post and read on these boards would like to be. Keep reading the posts, and don't be afraid to ask questions. I was told this little bit of truth by someone years ago, and it still holds true now.......the only dumb question is the one that you don't ask , because you don't want to look dumb.
