It would probably be worth it for you (and your husband) to go out with your step-father just to get some basic knowledge and familiarity with what you already have.
But going to a course for beginners, like one of the NRA offerings mentioned, would be a huge benefit.
Also, once you are a little more comfortable with the guns you have, start shooting some others; because you might find there is something available that is much better for you.
My wife is a revolver girl, but I think she has finally come to the decision (that I did a long time ago - but I didn't grow up with revolvers like she did) that the benefits of a revolver (reliability) are outweighed by the benefits of a semi-auto (capacity, speed of re-loading, recoil management) for defensive purposes.
