I'd do it at the very end, if ever.
But as was mentioned above, subsetting the fonts should be okay. This will remove all unused characters, minimizing the filesize while making it foolish to transfer to other books. This embedded font will also work much better across a variety of readers.
Nowadays, the easiest way to subset is probably through Calibre:
Method #1
If converting from another format, under
Look & Feel, there's a checkbox for
Subset all embedded fonts.
Method #2
Or in the Calibre Editor,
Tools > Subset embedded fonts.
Calibre Editor also lets you easily embed fonts in your EPUB with
Tools > Embed referenced fonts. (Although you'll have to already have the correct CSS.)

There are many other tools/methods for embedding/subsetting out there. A lot of this was written about in the great thread:
