In my opinion you should learn the basics. You firstly need to realise that you are not going to create amazing tunes in 1 week or month or possibly even up to a year. I recommend you just fiddle with all the music software, this way you learn how to make unique sounds.
I recommend that you don't use too many premade samples, this is because firstly you don't want to be dependant on other sources to make your new sound and secondly if you make your own samples its from your soul- you made everything.
An important thing is to just use individual drum samples and knock together your own rhythms, this way your'll learn d'n'b/ jungle drum conventions. A lot of ppl will help u on here.
But the most important thing by far is learning to design your own sounds by synth programming, I started learning in reason on the subtractor synth now im starting to use Reaktor building my own plugins.
I started fiddling with music software about two years ago and now all the pieces are falling nicely into place. You should definetly be a keen DJ this helps you find out what the audience likes in music and it is a very valuable resource. Also buy music production magazines such as future music and computer music etc, they have good tutorials on music theory/software.
