The big thing turns out to be making sure that your HTML is relatively clean before you put it into Sigil. It's easiest to make one big document out of your whole fic and clean it up in your favorite HTML editor before you import it into Sigil. With Old Roads, I spent quite a bit of time cleaning out old notes and such that didn't really need to be in the ebook edition--I downloaded the HTML of the whole fic from AO3 as my source material.
I then used calibre (http://calibre-ebook.com/) to convert the .epub into a .mobi edition for use by Kindles.
