Welcome to WebmasterWorld medugam.
How will you be importing feeds to your back office?
Perhaps you could export a feed of chosen posts by using something like Google Reader's favorites/Shared Items. Google even has tools to put clips of your shared items on your site.
There should be no need to edit the item's style. An XML/RSS feed shouldn't require that. It should conform to whatever stylesheet you're using on your site.
