You don't show anything about "setting up" the accelerometer at all. Are you feeding power by GND and VCC, or by other analog pins? If you mean the analog pins you declare, then you have to set them as outputs and write HIGH to the power, LOW to the ground.
Give more time for the servo to react? I see at least 15 milliseconds in most servo apps.
(And the ... tags are preferable to red. They'll retain indentation better and can be longer.)
