I would recommend you get the FAA PPL at any of the good schools who teach also for the JAR PPL. That way you will have a standalone US certificate to add the IR to later, and will also have been instructed in the ways of the JAA. A mysterious body soon to be EASA.
It may be an idea to actually do the JAR skills test here in Europe after a few hours with an instuctor. This time will also be useful for familiarisation with the local differences. With less than 100hrs you still need to do all the ground exams, fortunately.
(By the way JAR is JAA).
As far as where in the US to go : IMHO West is best.
