I would write to Baldor and ask them for the advisable drives, and power supply to use.
Ask them to be specific. Tell them your senario. Ask them what the output voltage/Amperage of the power supply should be. If they give you an answer you dont understand then tell them that, and ask until it is made clear.
I have asked the same questions many times until I have totally understood. You might look like a dork, but at least you finally get the right answer.
There are many parts in the CNC world that are intimidating. You are not expected to know every thing about it.
I looked at the specs you posted and dont understand them either.
