I turn off all automatic updates entirely. I still get notifications for available updates but at least i still have some control. I really don't like some of the new permissions of some of the bloatware apps. I would root just to uninstall, but in the long run it would make more work on me as I would have to reinstall to get future software updates. Perhaps after we get ICS and it seems stable.
I really think my next phone I will buy somewhere other than the carrier so I don't get this mess.
As for the laptop dock, not sure why you would need this in a car unless you were a police officer or paramedic (or something similar) but would think they would provide you a laptop anyway for the job. While I'm not one to oppose someone talking on the phone, especially with hands free devices (are we going to outlaw passengers soon?), texting/typing is way to dangerous.
