There is still a Stage 2 - the personality test that you did was the old Stage 1, Part B. Those tests you'll get in the new Stage 2 are pretty tough as far as I understand so I wouldn't go thinking too far ahead if I were you...
Good luck with your application - I'll leave the rest of the people on here to comment on Area vs Aerodrome as I'm yet to start college... Have you been to either an area control centre or a tower yet? Might be good so you can make up your own mind...
