Captainmasuk,
Being a Flying Instructor is a very enjoyable and rewarding occupation. It is, clearly, a very skillful task, but unfortunately this is not generally reflected in the jobs salary. In order to make a living out of instructing you really need to be working at one of the "major" schools, preferably as a commercial instructor. What L J R is saying is basically correct - to become a commercial flying instructor you need quite a lot of experience. To gain this you may have to work as a PPL instructor for "peanuts" for a few years so be prepared for that.
As regards exams and qualifications, I recommend that you knuckle down and get a JAA ATPL - this can only be a good qualification to have in the long run. The knowledge you will gain will put you in good stead for a career as an instructor. As the saying goes..."train hard, fight easy."
Good luck.
