Check your linkeage bushing (plastic). Dorman makes a replacement, these tend to break. In the mean time, you can Jerry rig it. I've seen people use zip ties to get by.

The end of the shift cable has broken, there is a plastic ring at the transmission end of the cable that breaks. You will need to have it towed to the mechanic.

What causes the "Reduced Engine Power", "Service Stability Control" and "Traction Control" warning lights to come on?

the "Reduced Engine Power", problem causes the PCM to disable "Service Stability Control" and "Traction Control" turning on the warning lights to come on for those systems . The reduced engine power is because of a problem with the electronic throttle control system or as GM calls it TAC system . Reduced Engine Power Mode
When the PCM detects a condition with the TAC system, the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
• Acceleration limiting--The PCM will continue to use the accelerator pedal for throttle control, however, the vehicle acceleration is limited.
• Limited throttle mode--The PCM will continue to use the accelerator pedal for throttle control, however, the maximum throttle opening is limited.
• Throttle default mode--The PCM will turn OFF the throttle actuator motor and the throttle will return to the spring loaded default position.
• Forced idle mode--The PCM will perform the following actions:
- Limit engine speed to idle by positioning the TP, or by controlling the fuel and spark if the throttle is turned OFF.
- Ignore the accelerator pedal input.
• Engine shutdown mode--The PCM will disable fuel and de-energize the throttle actuator.

Not sure if shifter is installed properly

Ok, I guess its going to be a not too obvious solution then. All we have to do is find it...
1.What type of gear shifter is in your truck. Column or tower
2. Is the tail shaft turning when you try to move the vehicle
3. Does the vehicle try to move at all
4. Is there any noise from the gearbox or clutch area
5. Are you certain the clutch kit was the right one
6. Did you try the clutch plate on the gearbox input shaft spline
7. Is the release bearing clear of the pressure plate fingers.
8. Does the release bearing carrier slide freely on the retainer on the front of the bearbox, and did you apply lubricant here.

Service engine soon light, service light, reduce power etc.

It is most likely the Throttle Position Sensor has gone bad. But if the check engine light is on, the only way to tell exact problem, is to have a scanner placed on the vehicle to have the codes read.

I backed the 2004 envoy into my driveway and the engine killed and the reduced engine power light came on along with service engine light also. Restarted the engine and had no throttle while in park...

You need to check the fuel injection system, throttle body, sensors, check harness for ground. Best solution is to have your engine scanned using Tech 2 scanner. The mechanic will advice you based on the scan code. Whenever the "service engine soon " light the computer system logs the error code. You can retrieve this error code using a scanner.

Manual transmission shifter will not engage

Sounds to me that the shifter broke, i believe the shifter has a ball end that slips into a pocket in trans. that moves for gear selection and that ball brook off end of shifter. if its got a linkage set up most likely samething either shifting arms came off or shifter broke where linkage rods connect.
