How do I enforce consistent plugins, pages, etc across my network?

I am using New Blog Template to create new sub-sites in my network with a mandatory template that includes a theme, a set of plugins, several custom post types with content templates, Gravity Forms forms and pages. Only the network admin has dashboard access. I am embedding the custom post types and views in the theme, so I can enforce consistency across the network in that regard. Are other changes to the template (plugins and configurations, new or updated pages, forms, media, etc) carried over to the sub-sites created using that template? If not, how do I enforce consistent plugin configuration, etc throughout my network?
