'02 Sunfire challenge for everyone

Here's a challenge for all installers, enthusiasts, and everyone else here.

I just got an '02 Sunfire GT. It has the Monsoon sound system with 8 speakers and an external amp.  Amp is located in left side of trunk.  This car also has the factory Content Theft Deterrent system, which according to other resources I've checked, can only be disarmed by using the factory transmitter or turning the ignition on. 

Challenge 1: I have a Pioneer DEH-P4400 which I will be installing. My book says '02 Sunfires use the Metra 70-2003T data retention harness(where you stick the factory deck in the trunk), however the book doesn't mention the Monsoon system.  Does anyone know if the Monsoon head unit hooks up the same way as the standard head unit?  Also, I'd like to integrate the Monsoon amp into the system.  Is there any way this can be done? It doesn't have to be an easy way. 

Challenge 2: The car has retained accessory power. Since the factory head unit doesn't have a switched accessory wire, is this feature controlled entirely through the databus from the BCM, or is there a separate relay or control wire that I can tap into in order to make my aftermarket deck have RAP?

Challenge 3: How do I get the factory anti-theft to arm and disarm without using the factory transmitter, or activating the ignition?

If anyone knows anything about this, please reply. It'll give me added satisfaction and credibility with customers to do a complicated install like this, and it'll potentially be helpful to others here who have monsoon systems, RAP, or factory antitheft.

Thanks a million

Sorry about this, I should have clarified it earlier.  I'm putting an alarm in, not a remote start(probably going to be a Viper 600ESP).  The factory alarm does not need bypassed for a remote start; it's called a "content theft alarm" or something like that, and is triggered by opening the door or trunk when the factory alarm is not disabled by using the transmitter.  I'm not sure yet whether it's armed by the doors being locked and closed, or by the factory transmitter. In the second case, I could disregard the issue entirely.
