Names, no names, the choice is up to you. It would depend greatly on how often those people move around or your rate of turnover (which is probably not all that great in a company this size?). Do what works for you. Oh, not sure that you actually have to name/show the silent partner, because if he is truely silent, he probably does not influence the daily operation of the quality management system (depends upon how silent he wants to remain

?) Don't think it would matter much. Make your system work for you.
What I see looks like it would pass muster, as long as you need an org chart (not required per the std, but a good visual way to meet the requirements) and that you do make sure to identify the management rep and his/her lines of reporting.
