Disklavier

I recently purchased a Mark III and am wondering what should I do 
now? 

Is there a FAQ section somewhere?

I'm learning to play the piano as a beginner (my daughter plays well) 
but in the meantime I'd imagine there has to be a ton of get 
performances out there I can download to make this thing sing. I'm a 
rock-n-roll guy would love to find some Elton John, Bruce Hornsby, 
Leon Russell, etc. Happy to buy if I need to but thought there must 
be some free stuff out there.

I've snagged a couple great collections from this group, downloaded 
an e-competition performance, and browsed some of the Yamaha store 
offerings. Beyond this group, are there some good repositories out 
there? 

I'm a bit confused about file formats. Is there a good primer?

My sales guy through in a bunch of stuff music on CD and floppy 
ranging from Nysnc to Steve Allen. Personally I prefer to hear only 
piano and not the other instruments. 

I've got the manual in my lap but my head starts to spin a bit 
whenever I read this thing.

Any good pointers for a novice?
