Thanks again for all the advice. Now I am all clear about the direction I need to take.
I have booked my first lesson with a studio Producer (orchestral percussion basics) and I am searching for a music theory teacher right now, so I can learn about harmony and counterpoint. It seems that I will need to start off at grade 1. Luckily I have a yamaha clavinova so I can practice on that.
I very much appreciate the time everyone has taken to help me make a decision.
James.
