Hi Steelpolish. Welcome to the Zone!
Congratulations on choosing a good lathe. You seem to have a lot to contribute, and I'm looking forward to following your build.
I have one reservation though--Your choice of driver/motors. The Xylotex will not hold up to any kind of production use, and the 91V 425s are seriously underpowered at 24V. My choice would have been G540 (Which has the C6 function & charge pump built-in and is unkillable), Keling 381s and 48V PSU.
When the Xylotex dies, get the G540. That and a 48V PSU will allow your 425s to work a little better.
CR.
