Red spark plugs

Also, I put a timing light on the engine, and the timing was about 29 degrees BTC. She thinks the knock sensor is bad & has another coming tomorrow. Could this be the cause of the (1) spark plug color, (2) performance loss, and (3) really advanced timing?

As far as the timing goes I think you have to may have to connect some electrical connections together first before you can check your timing with a light. I would check a service manual about the proceedure.
If the knock sensor is bad you will get a code stored in the ECU and I think the CEL light will turn on. This sensor is monitored by the ECU so it would know if there is a problem with it. They are not cheap to replace needlessly.

The timing, you really can't adjust the timing, the computer sets it based on varioius sensors, including crank & cam.
knock sensor, if it's never been replaced it's probably the old style which are known to crack and become oversensitive. There is a new style out that is supposed to alleviate these problems.
