If you are really ready to buy then go ahead and find a lender you are comfortable with and get a pre-approval letter (you will need this when you submit an offer). Then you need to interview several and then pick a buyer's agent to help you in your search. Give them the area you want to live in, the basic needs and wants you wish to have, and the time frame of when you would like to move. When you find one you will need to give them the pre-approval letter and make an offer. As I suggest with all my first time buyers and with some I sit and help but, make a budget of how much you want to pay in mortgage payments. Think about where you are looking. If you are looking at some condo, townhome, or even some single home communities don't forget to add the homeowner's association dues into your payment budget. Then between what you figure you can comfortably pay and what the lender has worked up for you with that payment maximum you can find something that you can purchase and not be stressed about. Atlanta has some very nice areas so just decide on where you want to be.
Good luck and happy house hunting
