It's not possible to record the audio of a phone call (other than with a loud speakerphone) as you are trying to do. This is intentional. You would need another approach off the device to do this. However, I can answer your other questions:

To make your application autostart, you can follow these steps: http://supportforums.blackberry.com/t5/Java-Development/Configure-an-application-to-start-automatically-when-the/ta-p/444748

Also, as this application above doesn't extend from UiApplication, you should check the "run as a system module" box as well, when you follow the directions above. That way it won't appear on the ribbon or as an icon in the list of applications.
