Hi :)

Welcome to the Trance Nation.
You definitely made a good choice.
At least I am absolutely addicted to this kind of music and the people are amazing.
Allow me to give you some suggestions though.
The intro can be 16 bars at a tempo between 128 and 140 bpm.
The intro can include kick, open and closed hihats and some FX.
After 16 bars comes the build up where you add a clap.
Again after 16 bars bars you can introduce the pad and that stuff plays for 16 bars. Then we introduce the melody and that part is called climax.
The climax can play for 16 or 32 bars.
After that comes the breakdown where many people just play their pad, maybe also open and closed hihats and or FX.
Then comes the breakdown where some people introduce the rest of the beat (kick and bass) again. That part can play for 16-32 bars as well.
Now we come to the outro where you slowly remove some elements.
To make the transitions smooth or cool professional people work with additional effects and/or crashes, reverbeated kicks and so on.
That's a little bit too much for you now, but if you use FL Studio I can explain everything step by step.
