NRA offers some good, basic training courses.
Check with your local ranges--some may have a one-evening familiarizaton class. Some have a CHL-prep class.
If you are in the DFW area, pm me and I will try to point you in the right direction.
I'm sure there are some good books, too...but many people learn best by first watching, then doing. This gives them the opportunity to ask questions between the "watching" and the "doing".
