RE: temp guage
Well the easiest place to start would probably be the temp sending unit and work your way to the gauge, sinceyou have already established that it is not a bad thermostat. Just a suggestion.

RE: temp guage
Most likely a bad gauge stepper motor, very common on this year instrument cluster.
Have your dealer reference GM Document ID # 2037454 which will cover the gauges under warranty for an extended period (7 years or 70,000 miles).
