The school your looking at will probably be very effective and is probably like most schools in that they teach from the ground up. You also might look into some schools that teach groud fighting or mixed martial arts. If you want to compete at a high level such as the UFC it is neccessary that you are not just a stand up fighter. And about your training, you might not want to drop weight at your size, 200 pounds is a good weight if you make it where you are mostly muscle. So train hard with weights along with cardio and eat as much protein as you can get your hands on. Many have the will to win, but few have the will to prepare to win.
