No, you don't need to remove the valve cover, or the coils, or any of that crap. Don't touch the top of the motor. The headers are on the side of the motor.
You will probably want to get a jack and some jack stands though, just to have clearance to crawl under the car.
NO, you can not remove the headers without getting under the car.
