For editing an EPub, I would look into sigil. It has the ability of WYSIWYG editing and comes recommended by other users on this forum. It's free and open-source.

For the rules that are added by the E-reader devices, I don't know a good way either. This page talks about a NOOK emulator, maybe that can help.
I found that the elastic straps of the cover I was using (one at each corner) had permanently deformed the nook st sufficiently to unalign the IR light grid over the screen. I'm now getting the nook to respond by bending the top front corners forward to realign the ir grid.(by placing my thumb at top front centre and my index and little fingers on the back ...
