Featured content

Good evening! I have a live site and am thinking about adding Featured Content (3 columns) to one page. Questions: 1. Is it possible to use the Featured Content on a single page that is not the home page? (For example, a test page.) 2. If not, is there a way of adding it to the homepage but not making it live until I have tweaked it? (As soon as I assign it to the homepage, the Featured Content template shows up live.) 3. Can I move three items (video, poem, and Facebook feed) from my homepage to this Featured Content thing? Will this be possible? My site is wellnesswarriorsboston dot org. Thank you. Alice
