But there are several source of how others have done it, which I have viewed and read many times, so it's about time I got going.

Can you explain that a bit more please.
How does stopping the spindle help anything? If the axes are still moving a stopped cutter will do nearly as much damage to the workpiece as a moving one. Don't you need an emergency pause button?
On the metal punching CNC that meant pressing the single step button. Then you'd have to press start for every line of gcode to progress and could sort out a bent edge or whatever at leisure. E stop was for when the sheet of metal got screwed up and the program abandoned.

Stupid question - you have a stop button - is there a physical cycle start button...single step button etc that I remember or is it all software initiated - click go on a PC screen or similar?

A lot of modern controllers have a restart after power loss. unlike the good old days, the code is stored in eeprom rather than RAM, so it remembers it's last known position. It also normally starts back up in manual override to so you can jog through the code and check it's position before it starts again. I swear that black magic is at work to do this.
