Before I buy a used one I wanted to find out and it’s a stupid question. 
 

What typical damage might affect final image quality? I want to think as long as the lens is fine, the lcd screen on back can be scratched or dented, and when I want to produce the final image it will be just fine. 
 

In other words, only a damaged lens or sensor will affect the final image?

And, if you are using it for AP (with a telescope) the scratched lens isn't an issue since you won't be using it.  If you don't use a telescope, then, of course, the camera lens matters.  A lot.  And the sensor.  Dead/hot pixels can be deleted during post-processing, if you are going to use processing software.  If you are feeding the signal into a computer, even the LCD screen won't matter - your laptop becomes the 'LCD Screen'.

Watch out a worn lens mount. It can lead to sensor tilt. Even a camera with a fine lens mount can have sensor tilt, and unfortunately it’s almost impossible to tell until you buy it and use it.
