You do not need to study for the FAA ATP. It is not like the EASA FATPL. You can get an FAA ATP once you have 1500hrs. The written test is easy. If I were you and after hearing what you have said do not do anything with EASA.
Save your money or if you have enough just go to the states and enroll in a course. There is no integrated system there, you do a PPL, build some time, do an IR, build some time, do the CPL then add a multi IR to it. It is a far simpler system and if you have no plan to work in Europe the license is just as recognized elsewhere in the world as an EASA one.
If you do not have a degree instead of worrying about EASA exams look for an online degree course you would like to do as this can hold you back in the US if you don't have one.
The cost of training to the same level in the US will cost you less than 50% of here in Europe.
Do not get an EASA license, not even a PPL, it is a waste of money. There are far better opportunities in the US, especially at the moment. 1st step find a school to do a PPL at. 40 hours and takes a few weeks at the right school, whilst doing that you will learn far more about this industry and what you need to do. One step at a time and that is the first step.
