What I do is is a lossless rescompress of the images. I use a value of 70. In most cases, the difference is not noticeable. But before the recompress, I reduce the size of the cover and titlepage to 1600 lines. Also, if there are embedded fonts I don't want, I'll delete them. I'll remove excess CSS classes as there can be hundreds of excess classes. And I'll delete HTML files I don't want such as review blurbs, other books, previews/adds for other books, mailing list signups, etc. And then any images with these deleted pages go as well. These things can make the ePub a bit smaller.
