I've done a bit of scratching around - read research and the answer seems to be mainly that what ever you did on the FAA is not counted and you effectively have to start again. Don't take that as gospel but perhaps the best idea would be to ring some local Flying schools and ask the CFI there and if you have real problems getting a straight answer, then post again and I can put you in touch with a guy who seems to know the JAA rules backwards, I've seen him help out not just myself but a couple of other guys in his interpretation of the JAA rules.
