** I don't know which template and section handles the Event Details display. **
That will depend on the template set you've chosen to use with your calendar. If the 'default' templates, the code will be in the <%-- EVENT VIEW --%> section of the default.html template file.
** I'd like to add comments to the template. Is there a preferred method, other than <!-- comment --> **
If you used <%-- comments here --%>, that tag will be parsed out of the page code before sent to the user's browser.
