Let me suggest that your best first order of business would be an NRA Basic Handgun class. There are good things about revolvers and good things about semi-autos. And there are the issues of understanding safe handling and proper shooting of both types of handguns.
FYI for the OP- NRA Basic Pistol course will be enough to qualify for your CWFL. Then you need a picture, application, fingerprints ($5 at your local SO), a check for $117, and you're good to go.
