I don't understand the significance of the word "seeped." Seep means flow, which it did flow into him, because thats how it was given to him, but that doesn't mean he hs an unlimited amount. And the past tense of seeped implies that it is something that happaned and has not happened since.

Naruto isn't a legitimate jinchuriki of all the tailed beasts as they aren't sealed within him. He had chakra from all of them inside him, which seems to be enough to qualify someone as a junchuriki but he has no way of replenishing that supply of chakra. Much like Obito didn't have tailed beast chakra left over.

To undo the Infinite Tsukuyomi he could have asked the Tailed Beasts again but only to undo it. Naruto isn't yhe type to hold onto something like that just without reason.

He may not have used 6PSM in the Last because of his lack of the other tailed beast it wouldnt be as efficient, his lack of experience with it, and the addition of the other half of Kurama, it may have been a better choice for him at the time. BUT THAT IS JUST SPECULATION ON MY PART. And after the Toneri threat he decided to get more accustomed to it in case he needs it.
