You will need the Enc module for rigid tapping, you will also need an encoder connected directly to the spindle.
Personally I prefer the old serial (Non-plugin) interface for the PLC but others seem to prefer the TCP.
I do not have to restart Mach after changes to the PLC but maybe that is a quirk with the plugin/TCP.
With Brains you definitely do not need to restart, you just need to reload them after any changes.
On my machines now I have a power button that switches on the computer, there is then a relay connected to the computers power supply that brings in main contactors which in turn power the 24v power supplies and the logic to my servo drives. This means there is a single button to switch on the whole control and then I have another On/Off integrated button to switch the mains to the servo drives.
Regarding your spindle and coolant, you really only need 1 button for each as in Mach they are toggle buttons, ie if off a press will switch on, and vice versa.
