Using Members plugin to restrict content to catergories

Hello all,

I've recently installed Jason Tadlock's Members plugin which allows restriction of pages and posts but I have built a site using a category template for the majority of the "pages". Could anyone tell me how to apply these restrictions to categories or to display the category template as a "page". Ideally, I'd like the links not to show up in the navigation either so that those who don't have access won't know what they are missing.

Thanks in advance.
