Also, to the first part of your question, the PCM outputs a PID called "SPARKADV". It provides the amount of spark advance being commanded by the PCM in degrees. It is actually a controllable PID with the WDS, meaning, you can command the amount of spark advance with the scanner.
My stock stradegy showed 16 degrees of spark advance at hot idle.
The Ford PC/ED manual lists the following values for this PID:
KOEO: 0 Degrees
Hot Idle: 15-20 Degrees
30 MPH: 29-38 Degrees
55 MPH: 34-41 Degrees
