Good that was all the small print; a quick 'translation'
1. You can get a restricted FAA PPL on the basis of your JAR PPL. You will have to go through a few hoops and collect the thing from an FSDO in the States. To that you can then add an IR. (Which you can then convert with some money and heartache into a JAR IR)
2. You can get an FAA PPL (unrestricted) by getting a medical (FAA AMEs in Europe) and do the written (AFT in Norwich) then go and do the flying either stateside (for issues relating to the visa look at the sticky at the top of the private flying page) or over here. FAA examiners over here in Europe can get you ready and signed up. You can do the flight test with AFT in Norwich or Stateside.
If you have any further questions, fire away!
