agree with RDR. get some nice synth and learn it inside out, and then you will be able to produce all genres on it....
there is plenty of great synths, but dont forget to check TAL-bassline (SH-101 SW clone). it's brilliant synth for bass and leads. easy to program and has excellent sound. on top of it, it's free.
also check for some tube amp plugin for fattening and adding nice saturation/edge to your sounds... D16 devastor, IK amplitube, NI Guitar rig, TAL Tube (free),......
