@Myth hunter Saying that Naruto doesn't need other wind release jutsus because he has the Wind Release: Rasenshuriken/Rasengan is like saying Naruto doesn't need to create only one Shadow Clone because he can create hundreds. What if he came across a situation where he needed a strong gust of wind, something which a technique like Gale Palm can provide but a Rasenshuriken can't? What if he needed to move something which only required one other person as strong as him, would he still make over a hundred? The chances of there not being another wind release user in the leaf is really low after all Minato, Hiruzen, Asuma, and Danzo had to learn it from somewhere. The reason as to why he didn't learn another technique, or maybe simply didn't use it, is most likely why the other people in the series didn't use techniques they obviously had, Kishimoto didn't want them using techniques outside of their fighting style because of... reasons.

As to how long it would take Naruto to learn other nature transformations, it would probably take Naruto after befriending Kurama a week, or two at most, because of his increased stamina and less dangers involved in comparison to last time, and it would take Naruto before befriending Kurama three to four weeks.
