Naruto trained doing different things than trying to control the Kyuubi.

Just like Sasuke trained doing different things, than besides becoming Orochimaru vessel
Kakashi and Konohamaru were still able to use clones. You don't need high chakra reserves to be able to use clones. So stop trying to use chakra as a down side when you don't need to spam clones like Naruto.

That doesn't change the fact that the main focus of the training was for Naruto to learn how to control the Kyuubi's power.

What are you talking about? Everything Orochimaru trained Sasuke for was to become his new vessel. He wanted to make him stronger.
