Tutorials translations are appreciated.
Simply go and use the "Know another language? Translate this tutorial!" in the left bar of any tutorial to begin a translation of it.
I don't think there's a need for a request or anything, this is a community effort, and I, for one, can't speak Spanish, so wouldn't be able at all to translate my own tutorials in Spanish.
If you feel like translating them, go ahead :)
For the manual, atm, there's only English but translations for it are also planned in the long run.
