I have a 2003 Monte. I've owned it for 5 years now. Been a perfect car. The last 6 months or so I've had tons of problems and not sure what to do with the car. I'm afraid of being taken advantage of at the local dealership without knowing all I need to know before I walk in the door. My car has many problems and I'm pointing more in the direction of the BCM or the ECM as the problem. I keep a list of what its doing or have done in the past. I also have a video of it doing these things.

The transmission slips occasionally. This puzzles me because it's only once in a while. Maybe once a week or it could be every time it shifts in a day, just depends.
When I'm on the highway and pressing on the gas I can feel the car pulling, like pulsing, not sure how to put it into words, but it has a hard time picking up speed. I can see the RPM gauge fluctuate when it does this and the check engine light will flash when this happens. When I punch it, it will take off just like normal like nothing was wrong, the check engine light will stay on but quits flashing. Repeat this all the way home.
Sometimes the lights won't go off inside or outside the car. We had to disconnect the battery for them to shut off. This problem has killed my battery many times.
Security light comes on and stays on while I'm driving the car.
There is a crackling/popping sound around the glove box area when I shut the car off. This sound will happen when all the lights on the dash, headlights are flashing and the truck popping/clicking all together.
The door locks pop lock and unlock over and over
The truck tries to pop open (but for some reason will not work anymore without the key)
The dash will say the truck is open but it's shut.
Check engine light flashes.

As you see there are many things going on. Any help would be great. Thank you for you help and time.

I agree that the BCM could be the culprit for the lights and locks.

The flashing CEL means you are misfiring. When was the last time the plugs/wires were changed?
