Welcome, Mathew.
The previous replies are spot-on with the info about research and asking questions. You might run into a few jerks out there, but the large majority of the gun culture likes to help others. Be patient, do the research and it will all come together for you. I did the same thing 21 years ago, right after my 21st birthday, and CCW has been a goodly portion of my everyday life. It is a responsibility to take seriously and you sound like you are working in the right direction by seeking advice.
Good luck,
Peg
