Don't get me wrong - but I have this feeling that you are somewhat rushing.
Why don't you contact CTC and tell them you would like some more time to get prepared for Phase 3?
I applied in November and have Phase 2 on hold and I am thinking to further put it on hold until I finish my degree.
As for choosing between Microlight or Cessna 152, a Cessna is more close to an "aeroplane" and is more fun in my opinion rather than a Microlight.
