4. Your driver's license is required only for driving. If you are not driving then you don't need to show a driver's license. In Kentucky's concealed carry law all Kentucky CDWL holders must show their license if they are asked for it by police if they are CCing. If you are not breaking the law and an officer does not have RAS then you are not required to produce ID.
5. Probably read HERE, it is most of the laws you'll ever need for carrying a firearm in Kentucky. It even has links to the actual laws I think supports my opinion.
