I'd just fly for fun here and wait until you get to Florida to do the rest. You will need 250 hrs to do the FAA CPL but of course if you are going to do the IR then that will use up 50 or so hours.
I'd go to florida and convert to the FAA PPL and add the IR. Then train for and do the FAA SE/ME CPL. I'd then add the initial CFI rating, then the CFII and MEI ratings. You might find that if you choose your flight school in Florida carefully that once you have finished your training they may offer you a job as a FI.
I certainly wouldn't bother with the JAA ATPLs at the moment, though if you wanted to continue training you could do worse than going to the USA for a few months and doing the PPL/IR.
(I'd go to California as Florida is flat and boring and full of old people
