There is software that will download/rip websites for you, both on tablets and computers but I'm not familar with them. I think they start with a W in maemo extras and extras-devel. However for RSS feeds you can use what I'm using, feedcircuit. It's no longer updated by the author but is really customizable but it takes a long time if you have lots of RSS feeds or heavy RSS feeds. I have around 40 rss feeds of blogs, reuters news (screw AP), comics, and other sites I use feedcircuit with and it'll take about 40 min to an hour to do all of them. But it comes in handy on the DC Metro where you likely wouldn't even get service lest your on Verizon.
