First some good news, the officer will not show up unless you subpoena him, don't do it. The only evidence presented will be his statement.
More good news, he does not state he tested his radar unit that day and does not identify the tuning forks so move to suppress any reference to radar measurements before his statement is read into evidence.
I will let others reference what is required for his speedometer. I suspect that since he does not identify his patrol car by any unique means (VIN, plate number, etc.) that would be grounds to suppress his speedometer readings. since any speedometer calibration data cannot be linked to the incident in question. Since the vehicle is not identified there is no way to demonstrate that the speedometer was or was not working properly.
The rest of your arguments not relevant and will not help you in any way.
Also, the standard to be found guilty is preponderance of evidence, not beyond reasonable doubt. If the speedometer reading/pacing is allowed as evidence you will almost certainly be found guilty.
