Well I don't know neither wilco (I don't play MFS for my training) nor the real airbus since I actually fly another type,anyway I'd suggest you to study just ATPL books and POH of aircraft on which you are learning VFR/IFR flight.You will have time to read a lot of stuff about airbus,boeing,fokker or whatever jet/turboprop you'll fly,doing it with a strengthened background and being assessed by professional instructors throughout ground and simulator sessions.Enjoy your 19 yo,meet girls and fly the Cessna/Piper doing your best to pass CPL exams.
Bye
