I'm going to assume that you don't have any virtual instruments that you can use either standalone or as DXi/VSTi plugins when I say:

No. You get a loop-based multi-track arrangement interface, but it won't do you any good without something else you can use to actually create the loops.

No.

Maybe. I know it has a multi-track interface similar to Audition, but I don't know if it comes with any instruments.

Which is now Audition. No.

No.
You'll need a sequencer/DAW. I personally like FL Studio and am given to understand that it works well for the type of music you're describing; you may also want to check out Ableton Live, Twelve Tone Systems' Sonar (Windows only?), Steinberg Cubase, Propellerhead Reason, Apple Logic (Macintosh only), etc. etc.
