There is no real limit to the number of coats, I often apply a fresh coat in lieu of polishing, or before going out on a rainy day. You may need to work the leather a bit with your hands to get softer, if it was super stiff to start with. Not sure what you mean by absorbed into the inside of shoe, it should certainly saturate the leather, not just sit on the top of it. I will often "paint" the inside with the oil as well to speed the process, and maybe wear the shoes around the house a while to work the oil through.
