So to this, does anyone have any settings I could try to get this Orion SSAG to work with PHD and a 1000mm or longer g/scope under average seeing skies of 8/10ths?

Jabar, you'll have to adjust the settings in the "Brain".
You want to adjust the maximum calibration step until it can complete each direction in around 15 steps. I'd guesstimate a value of around 1000 to get you started. Make it smaller if it takes less than say 12 steps and larger if more than 18. Different combinations of camera and scope require a different maximum but once you work it out is should stay the same.
PHD wants the calibration star to move about 10% of the way across the guider image, so for an SSAG that's roughly 130 pixels. That's about 145 arcsec at your image scale.
Don't forget that it will take 15 times the exposure + download + calculation time, so with a 1 sec exposure calibration will take at least 4*15 sec.
