I have tested this feature (multi-language ez-pages zc v1.3.x) extensively.
Here are my results:

- There is no way to create or edit a link for the ez-pages section in the shop
(e.g. header, sidebox, ...). After the clicking the "INSERT" (or "UPDATE) button,
the same site will appear with empty page title fields.
(in Tools->EZ-Pages->edit/new_file ->insert/update))

- The footer (with the ez-pages) do not appears in the shop. I have used suitable
settings, e.g. EZ-Pages Settings (configure menu)

Maybe this can help you a little bit.
