I had the same problem before, (when i replaced my alternator) had the battery unhooked. It would die when running the A/C or heat anr had a rough idle. You mite want to have your Cam Shaft Sensor reset that fixed the problem for me, Hope this helps

You almost certainly need to clean the throttle body. Cheap and effective idle enhancer:

The clicking on start, with a new battery, is almost certainly a deteriorating ignition switch. Again, a cheap and easy repair:

On the universal remote - do you have a learning remote, or are you trying to get one that already knows GM codes?
Is the clicking when you TRY to start the TB or after it starts do you hear clicking, about once per second? If it is after it starts it is the fan clutch starting to go bad.
Once you disconnect the batt there is a learning curve on the PCM. However you still need to do the throttle body cleaning WITH the battery disconnected for at least 20 minutes.
