In marking out your template first decide where your clips are going to go. There will be one at the back of the zip and 2 at the front, there will be one on each (corner, I use the term loosely for if this is a large radius you may space 2 closer together ). A handspan (octave) apart for the others, bearing in mind you don't want to rest your arm on one.
Now drill your clip holes, to which you will screw your template. Keep tension front to back and let the sides fall loosely to the clip(screw). Mark your final hole positions and use the template to mark out actual fabric to be used, screw this back on your car to check fit and punch holes in your cover. When the tonneau comes back from the sewer( that's s o o wer), you will have more success fitting clips to these accurate holes.
Many cars have a steering wheel protruding above the bodyline and you may need a dart or pocket here, a dart is simpler and can terminate at a clip. Be sure to mark the ACTUAL sew line and then ALLOW an extra allowance of say 10mm .
You have asked how much overlap( I presume you mean body overlap) , I would aim for 50mm.
Good luck Russell
