He's taking off his clothes and diaper because toddlers love to get naked. This has nothing to do with potty training.
Get a good potty training book that lists the readiness signs. The more signs he shows, the faster he will learn. Does that mean you need to wait until he shows all the signs? No. It just means that the less ready he is, the longer you will be training. No matter what age you start, he will finish learning at the same age. So you can start at 15 months and be training for the next 15 months or you can start at 25 months and train for 6 months. These are examples by the way. The point is that he will finish learning when he is ready - regardless of his age when you start.
