The Catalytic Converter is supposed to run hot, but it shouldn't glow red. If it is glowing then you are getting raw fuel to it usually because the engine is running too rich or maybe the cold start valve is open or leaking. The high idle speed is caused by someting not set-up correctly, vacuum leaks, or maybe sonmeone switched the plugs on the cold start valve and the pressure regulater, that is only supposed to be done for a short time to test for a bad fuel accumulater. Be sure to plug the access hole above the mixture screw or you have a massive vacuum leak, you really shouldn't mess with the mixture as it usually isn't too far off and is very sensitive. Check the 3 brass screws on the intake, they should be lightly seated closed. Check that the throttle plates close all the way, the floor mats aren't keeping the pedal from retuning all the way.
