Rss feeds

Hi all I am setting up a news site and was looking for a rss feed that will automatically grab rss feeds from other sites . I would like it to take the full article and then to give the articles source either at the bottom or top of article . Would have to suit WordPress ! Any ideas
Also looking for a theme for a news site , want to keep it similar to the way the news comes in now on the home page with the latest on top with image and older ones below with a 1 line intro, http://www.newsonline.ie any one any suggestion s
Thanks
