whats the best way to handle all these +5 volt connections since there is no where to connect them all .
You have a few options for spreading the 5V to all your drives. You could bring out one or two wires (what ever you can get into the 5v terminal), and then daisy-chain the jumps at the drive connectors with little loops. YOu could get a crimp 'splice' connector and bundle 4 wires and splice it down to a single wire, or you could get a little terminal strip and stick it off to the side. No right or wrong way really.
Your lists look good, nice work. small comment, I think your schematic a few posts up has the direction and +5v wires swapped.

When you get to the point of needing to setup the software side in UCCNC, your table/list will help alot and it will make sense, as you've listed what output is what signal for what axis, etc. Then as you get it setup and working, you'll want to make additional note of what is active low or not for certain signals, etc. Some of that will be easier to figure by trial / error while setting up.
If you haven't done so already, start making notes of your steps per units setting for each axis, etc from Mach3.
