Well if the JAR thing is a shambles you will be comforted to know that the NPPL has been dreamed up by the same organisation that dragged GA into JAR-FCL. AOPA!
The NPPL is likely to appear next year despite the fact that few actually support it. It is of course a CON; if the same course took 55 hours two years ago how can it now be done in 32hours? unless you go to Florida!
The NPPL Instructor part remains a mere proposal, and unlikely to get off the ground until the NPPL has established itself as a raging success. How long will that take? quite a few years at best.
My advice is to take the JAA CPL exams and do your instructor course especially as you are well on your way.
