Ludvista, you already have the right tools to start.
If I were you, I would open up some rex files and listen to the DnB rex's. Those helped me a lot to get an idea of what DnB should sound like, roughly.
Also, LISTEN LISTEN LISTEN to DnB. I listen to DnB everyday, on the way to work, on the way back, during work, at night.... Your mind starts to think that way and you start to get accustomed to that style of music.
Practice, experiment. Don't be afraid of sounds, use them, ANY SOUND.
Some people think that certain sounds should go into certain songs etc... A myth, in actuality, some of the best songs used new sounds or sounds that were never used in that genre. Just experiment.
