You're in 4 a treat, now that you've got the input mappings that's a start. The leds are output mappings and those are a little harder. Go too this page
viewtopic.php?f=401&t=19330 and hopefully you get to know how you've got to map them.
The only person that knows this kind of stuff and is willing to help is FigDJ, he does this in his spare time
The bad news on this, don't count on the MV staff cuz you will be death and buried before you're leds are mapped
