PPL152,
One small hiccup with your plans.
I am very reliably informed that Spain will only issue a CPL provided you have a Spanish medical and that you have undertaken both flight and theory examinations in Spain.
Does Spain recognise Bristol GS and / or GTS as an approved training organisation for pre-exam theory studies?
I am studying with Bristol and I was told by a Spanish FTO that the Spanish authorities would not permit me to undertake the exams unless I had studied at an approved Spanish FTO (but that may have been sales spin so you would be advised to check with the authority itself).
I am even more reliably informed that the Spanish authorities can be extremely anal (and this source of info I do trust 100%) so be careful - do not tie yourself into any chain of events that are not compatible with the route you wish to take.
As for the FAA IR, no problems. It's an ICAO IR so just requires the JAA theory exams, mandatory 15 hour conversion course and flight test.
HTH
