Personally, I like Cliff Jacobson's books and DVD's:

I have found this DVD to be especially useful: http://www.cliff-jacobson.com/forgottenskillsdvd.shtml
Note: A VHF radio will be useful only in areas that the U.S./Canadian Coast Guard, or other rescue agencies, monitor (e.g. costal areas, the Great Lakes, etc.).
There are many areas, for example, the Adirondacks, in which a VHF radio will not be able to summon help.
See you on the water!
