Congratulations ...
Great news! Now, I want to suggest something that others may differ with ... but, I think the biggest adjustment you will make is in philosophy.
Previously, you (like me) played the odds. You
hoped you'd never need to defend yourself and innocent others against lethal criminal force. Now, you've taken responsibility ... we call it 'First Defense' at Mothers Arms. Just as first aid preserves life, you will defend innocent life until the professionals arrive. You need to get used to carrying your firearm, practicing, and as you note, learning the laws that affect you.
I don't know diddily about GA law ... others will likely respond. Here's a helpful web page -

You will probably have some judgement calls to make. I'm not recommending that you violate any laws. By the same token, honest LEO's will tell you it is better to be judged by 12, than carried by 6. Get to know experienced folks in your area, and find out what 'prohibitions' are simply not enforced or practical. Sometimes such practical considerations exist. And, if you carry in a very discreet manner, no one need know that you are prepared to defend innocent life. But, weigh the costs and benefits.
I'm not suggesting you break any law. You should learn the law. However, Suzanna Gratia Hupp watched her parents be murdered because she left her sidearm in her truck. Like I said, you have a number of choices to make.
You and your family will be safer if you take appropriate responsibility for using your new safety rescue tool. Seek more training, practice, and secure your firearm responsibly.
Good luck, congratulations and ... always be safe and responsible. Wear the 'cone of peace'.
