about feeds is a bit complicated
I would recommend
http://www.feedbooks.com/
Here u can upload in to one file or newspaper including all feed that u want to reed or choose from thouse already listed like BBC, MobileRead Forums, The Economist.
Just simply log in and then choose supported format
Hope that was helpfull
P.S> I would recommend that u choos RSS sites with longer content, becouse some sites have only very short version of articles.
