See Rob Hanus’ reply for the first part. Books take up a lot of room. Here’s where that Kindle shines. And you’d best collect a lot of reference material on it. I’ll bet your cell phone has a lot of useful tools on it, too. The cell towers might be down, but if you protect your phone, it will be of use for some time. Store spare phone batteries or backup batteries. Think about emergency radios. You can get them with a hand crank and a USB-out, so you can keep the radio charged and charge other USB devices. If you have an Iphone or other device without the standard USB connector, get an adapter. Also beware that there are both micro and mini tips. Get the right one.
In addition to critical infrastructure, I’ve hardened military and government facilities for 32 years. What’s required to harden a facility is to create a 6-sided electromagnetic shield around the equipment that’s intended to be protected. The six-sided metal shield has to be constructed so it basically has no openings in it except those that are absolutely necessary to have. And all of those openings are technically considered to be points of entry. So you start out by building a six-sided metal box with no openings, and then you start adding openings for things like the electrical power, communications and air exchanges and cooling systems. And all of those points of entries are handled in a very, very special and particular way in order to ensure that you are attenuating any EMP signal that might be broadcast in the atmosphere, but also any signals that are being brought in, conducted on the electrical lines or communication lines.

Transdermal patches (adhesive patches placed on the skin) may also be used to deliver a steady dose through the skin and into the bloodstream. Testosterone-containing creams and gels that are applied daily to the skin are also available, but absorption is inefficient (roughly 10%, varying between individuals) and these treatments tend to be more expensive. Individuals who are especially physically active and/or bathe often may not be good candidates, since the medication can be washed off and may take up to six hours to be fully absorbed. There is also the risk that an intimate partner or child may come in contact with the application site and inadvertently dose himself or herself; children and women are highly sensitive to testosterone and can suffer unintended masculinization and health effects, even from small doses. Injection is the most common method used by individuals administering AAS for non-medical purposes.
