Training is a good idea. Most folks seek out training at their local gun store, Gander Mtn, etc. They generally have some decent beginning training classes for cc and self defense, and after you get more familiar with shooting you can seek out more specific training to fit your needs.
Some folks are lucky enough to be friends with good instructors and will train with them in their spare time - that's what I do when I get the chance. Personally, I like running more practical concealed carry drills - mock ATM robbery, parking lot encounter, restaurant encounter, etc.
