I would recommend driving, i do not remember going past a station on the way down although, there was an airport nearby!
Stage 2 can be broken down into:-
Another motivation paper, a little harder than stage one, i would recommend reading the resource over a couple times and checking out the airport and airline codes.
There is the interrogation, bascially lots of question in quick order. Mostly standard interview types with some personality types thrown in for good measure. All thick and fast and they will expect you to elaborate on each answer.
Lastly the computer tests, there is not really much i can say about these that'll prepare you any better apart from, stay relaxed and that everyone believes they have done badly on them.
Otherwise, good luck and hope you get through
