Welcome to the forum.
A temporary drivers license to be shown in a gun store in GA (I sell guns at a local FFL gun store in Smyrna) is a perfectly valid license, for the purpose of completing a 4473 and purchasing a firearm. You won't have to wait until the permanent DL is mailed to you.
As to buying a gun from a private person, sure, you could do that. I personally would ask for a DL and a carry license, if I were selling to someone. But there are lots of folks who will not be that careful.
