This is a more general comment and you probably already considered this, but is this going to be a 'canned' course or tailored specifically for each group? One of the challenges I've encountered, and in fact am working through right now for a presentation for a worship technology conference, is that not only the services, facilities and goals of churches but also the tools, equipment and resources available to them can vary significantly.
Unless you are presenting to one group at a time and can tailor the content for each, then I find it much more effective and less confusing to address more general topics and concepts that apply to most or all of the attendees rather than getting into any specifics that may not only be irrelevant to some but could potentially even lead to people erroneously assuming that everything presented applies to every, and specifically their, situation. Too many experiences with people that attended a class or training session or read a book and apparently gained the impression that everything presented was an absolute and applicable to them, even if it was actually personal opinion or preference or was irrelevant to or inappropriate for their situation.
On the other hand, if your plan is to offer training tailored to each group to which you present, then it can be very effective, and more interesting for the attendees, to try to specifically address their situation and address the practical implementation of the topics in that context.
