I believe the one you're referring to is Naruto Episode 58 Hospital Besieged: The Evil Hand Revealed!
The episode you are referring to is "Naruto Shippuden" Episode 32, titled "Return of the Kazekage." In this episode, Sakura and Gaara are discussing the Sand Village's future and Gaara shows her a room with books that he has been reading.
In none, it never happens.
well none
I'm not sure what episode becase its been a very long time, but I think it was when they were fighting gaara and he pinned her to a tree
No, Naruto is friends with Gaara but has a crush on Sakura.
no
she's not
No. Never. Gaara has no romantice or lovey-dovey moments.
I don't know the episode per se but I know it's the rescue Matsuri-arc, in the fillers. Around episode 118, or maybe it is episode 118. I don't know.
Yes he does,in the Forrest of death while Gaara was trying to attack Sasuke Sakura jumped in frount of Gaara to pertect Sasuke but Gaara pined her to a tree with his sand to keep her out of his way.
She doesn't. She finds out about Naruto and the Kyuubi when Naruto tells her during the Save Gaara Arc of the Anime/Manga.
Sasuke saves Sakura in Chapter 181 of the Naruto manga.
