Interesting analysis. Re. the PCB headers, the only caution in a high noise environment is the protection of the '14 inputs to >5V spikes. The IC should have clamp diodes that should work to protect but worth bearing in mind.
I have to admit all my cheap boards have had opto isolated inputs which I think can only help for noise immunity for systems like this.
