What I do is use KindleUnpack to shift from KF8 to ePub and then I have a look at the ePub in the editor if the ePub is OK enough, I'll run epubcheck to check for errors and then I'll fix the errors. If the KF8 is not good enough to shift, I'll do a conversion.

After that, I'll remove unused CSS and losslessly compress the images. I'll also rename the HTML files to something that makes sense. And from there, I'll do my usual cleaning up.
