I've been doing the same thing.

1) Get CPR and first aid training from the Red Cross, Heartsaver, or another certified organization. These classes will provide basic manuals with the hand on instructions. These are more of the Check/Call/Care instructions then anything advanced. Take Advanced First Aid, Wilderness First Aid, or First Responder training for the more advanced techniques. The training will provide needed hands on practice, and the certification will also provide some legal protection under the "Good Samaritan" laws in case somebody dies or is injured while you're attending them.

2) Get a first aid book, separate from any printouts in your binder and keep it with the FAK. The Red Cross has a first aid manual. I've got a copy of "Everything first aid", which is written along the same lines. Also, it keeps blood off of your disaster binder (I'm not kidding, I've bloodied up several kits patching myself up).

3) An advanced book (e.g. wilderness first aid). This is strictly a SHTF measure for when ambulance services are not available or severely delayed. It will NOT offer any legal protection, but I think its better than having no idea what to do.

Last and legal note: If you're treating someone you need their consent and they need to be informed that you are, or are not, certified for a particular technique. The last first aid course I took said nothing about the old "unconsciousness = consent" law. So I'm not sure it's still valid.
