I don't think the manga ever showed the original Shinju. It can't really be said that it did or didn't have the Rinnesharingan. Either way both Madara and Kaguya obtained after recieving power directly from the Shinju so it can't be said that these abilities are linked to Kaguya. And technically, the tree did become the 10 Tails.

Giving people the ability to produce chakra and giving them chakra is essentially the same thing because without the Shinju chakra wouldn't exist. Its like saying Kakashi's Sharingan allows him to use its techniques vs Kakashi can use the Sharingan. Quit with semantics. Plants have physical energy by the way, as they grow and perform physical functions.

No,Kaguya is not needed for 6 Paths Chakra. The Shinju is.
