Do option 1 - but do the Jaa atplh stuff by distance learning at the same time. I am in a similar position and it is quite hard to learn 2 sets of slightly different rules of the air but I'm sure you'll get your head round it!
That said once you start instructing you won't be studying the fars anymore and, depending on the school, you will certainly have enought time on your hands to complete the ground school bits in well under 14 months.
The distance learning course seems to be about £3k .
Good luck!
