Still planning... Do I have all my parts?

[Turf]

Hey there boys and girls.  This is my first post here.  I know ya'll get a bunch of first timers here so what's one more right?  Anyway, I wanted to run this by all you old-timers out there.  I'm working on my part list for my CP.  I'm about to start buying my parts and need to know if this is all I need.  Here we go
 
1) U360 x2
2)Electric Ice T trackball
3)LED-Wiz x2
4)Electric Ice buttons w/ RGB board, LED, and all included x19

I think that is all.  The LED-Wiz will control 32 inputs, right?  3 for each button and 3 for the trackball.

3 x 20= 60 inputs needed
2x LED-Wiz = 64 inputs

As for the pushbuttons, the U360's allow 8 and the trackball allows 3 right? 
I'm a full on new at all of this so just bare with me.  I'm doing my best to research before asking stupid questions.  I just don't want to buy a  bunch of stuff I don't need or won't work.

Welcome. Sounds like you've done your homework.

So for your 8 inputs, is that 6 per player plus start and coin? Are you shifting everything else or just relying on a keyboard for any admin functions?

That's 6 player buttons, start and coin on each U360.  Then on the trackball, I'm planning on exit, pause, and shift (I think the I'll put shift on there).  I'm also planning on using a drawer for a keyboard and mouse.  That would probably be easier if/when anything goes wrong.  Thanks for your help man.
