Even though we've previously seen Naruto as distant from his peers, this episode shows him running out of class with Kiba, sleeping like Shikamaru, and eating in class near Choji. What's more, they all have the same lax mindset toward Iruka's leaf-related method of teaching. This, however, does not conclude that they were "friends".
Jiraiya: (Thinking) This kid is something else. The chakra was so dense it burned his palm. One surprise after another.
Naruto: (Laughing hysterically about the scene of Jiraiya with the ball in his mouth) How can I concentrate with that stupid perv's face popping into my head?!
Jiraiya: (Thinking) There's no other way, Naruto. This training you must do alone. You can attain the level of the Fourth Hokage someday, but you must grab it on your own.
Naruto: Ya lousy bum.
(Naruto throws a rubber ball at Jiraiya and Jiraiya catches it with his teeth.)
Jiraiya: Strike! (Laughs and spits ball out.) There ya go, kid, game over. (Laughs) See ya around, sport.
Orochimaru: The best medicines are always bitter.
Young Kiba: I can't just stay put at a desk. Right, Akamaru?
(Akamaru barks and Shikamaru yawns)
Young Chouji: I'm hungry...
Young Naruto: Sensei, please keep your lecture short.
Orochimaru: (Groans) My arms!
Man: Are you okay, Orochimaru? You must take your medicine, quickly!
(Orochimaru slashes the man, causing him to bleed all of the floor)
Kabuto: I just came back, and I need to clean the room already?

To help him concentrate his chakra better. Naruto changes the spiral on his hand to the leaf symbol on his forhead protector. This comes from an old exercise Iruka tried to make him do which helped to mold chakra.
About halfway into the episode, when Tsunade is at the slots machine, she gets three 7s in a row. When you see the slots symbols, you can see a leaf, a snake, a slug, and a frog. These are all references to the Sannin.
Tsunade's companions are Shizune and her pig, Tonton.
With his jutsus all sealed, Orochimaru is forced to use Kabuto to perform the summoning jutsu. As shown in the past, Orochimaru is able to summon snakes.
