Reply to Production: 5 Basic Questions that I need answered.

Hi!
I have reason 5 for software, novation launchpad for hardware (i originally got for djing with traktor) and a Midi Fighter pro (which I can also use to control Reason, no?) I have had reason 5 for a while but never learned how to use it.
1) What other MIDI devices that are fairly cheap should I get that would be better for beginner production?(was believeing like a MIDI Keyboard??) Maschine?
2) How do I map my hardware (hardware in general) to Reason?
3) How can I add some different sounds to reason? (aren't they called Refills?) where can i get them?
4) What about VST/ AU? do i need those? where can I get them? Free or paid for?
5) What else might I need to know that I might have missed?


THANK YOU FOR YOUR HELP!
Also to those of you that may have something negative to say about my knowledge of Production... YES I KNOW IT'S LITTLE TO NONE! THAT'S WHY I'M ASKING FOR HELP!
