http://beprepared.com/product.asp_Q_pn_E_EB%20F100_A_name_E_A+Comprehensive+Guide+to+Wilderness+%26+Travel+Medicine+Book A Comprehensive Guide to Wilderness and Travel Medicine by Eric Weiss MD is also good. Its more adventurous than the Tilton guide, will even talk you through an emergency tracheotomy if that's the only option you're left with in the wilderness.

In terms of training I say any that you can get - Red Cross is usually in your town and operates like clockwork, CPR/AED is standard and should be kept up, and their standard first aid class is okay. NOLS and the Wilderness Medicine Institute run the gamut of training, everything from 2 day intros to 2 week classes for more advanced first responders. http://www.nols.edu/wmi/courses/. I was impressed with how comprehensive the WMI course was, with a good balance of classroom and hands on reaction to simulations (about 40% classroom, 60% hands on). WMI typically comes to or near your town a few times a year, look at their schedule and contact them for the next course in your neck of the woods. The instruction is tailored for when you are away from emergency responders, such as 2 hours or more up a trail and hours from evac of your victim, which makes wilderness medicine a pretty good fit for post-disasters and other emergency situations. Its made me more comfortable with lots of medical situations we're likely to encounter after an earthquake for example.
