How long should the ECM take to "relearn" and adjust the idle speed down?
Any suggestions on what to do next? I will not be driving it anywhere until I know I can trust it to keep running and not burn up.

It won't happen sitting in the driveway.
If I remember correctly one of the conditions for a self learn of the IAC position is a 45 MPH threashold must be met.
You can try this and see if it gets closer.
Using a watch or timer to make sure you hit the times on step 3 and 4:
1) Disconnect battery for at least ten seconds. (with the Key OFF)
2) Reconnect the battery.
3) Start engine letting it run for five seconds.
4) Turn key off for ten seconds.
5) Then start it and see how it idles.
