I'm traslating the wiki in Italian (I only translated a page since now), should I write something like "Traslation not finished yet" on that page?

No.

The wiki guidelines don't say anything about translating, although I'm sure it would be best if entire pages were translated at once, instead of only partial page translations.

I would thinkg though, any effort is better than nothing, and a wiki is a great place to start, as others can pick up your work where you left off.

I translated an entire page, I meant "Wiki not fully translated into Italian"

No such disclaimer is needed anywhere. Also, thanks for translating.
