Do not worry you will get it down. In about six months you will have all the basics down and will be able to do some real damage. At least you have a martial art background of some kind. MT was my first martial art. My weight was 280 pounds of pure fat. After all that intense conditioning I am in real good shape. That is one of the reasons why I love MT. Your instructor will correct your mistakes. If you do not know something then ask. Get a bag at home and practice practice practice. The stance and techniques are straight-forward in MT.
In my opinion for MMA boxing, muay thai, wrestling and bjj are real good. Your judo and jjj will come in handy as well.
