To edit your facebook RSS import settings do this:

I just spent about 20 minutes trying to find the way to change what rss feed I am importing in my facebook account and everybody that I found via google gives a click this click that response which is not very helpful if you there is nothing to click that corresponds to what they are saying.

so here is my solution: (copy and past the following)

http://www.facebook.com/notes.php?imported#/editnotes.php?import

That should work.
