Juubi jinchuriki can use dojutsu, Obito just disnt have enough control yet to do it.

The science division wouldnt have to go to the moon to have an accurate estimate of the moons mass. Point is, they had some way to calculate the mass with enough certainty that they could say whether or not they had enough chakra to blow the moon up.

Hashirama was strong enough to restrain it, not kill or fight it. Sealing jutsu also do bypass strength to some degree.

Naruto could sense Sasuke with senjutsu while he was on his way to save Sakura

Shizune didnt deny Sakuras strength. Regardless by the end of the manga we have confirmation that it was true. Hashirama may have learned about Tsunade's strength and abilities from Orochimaru/Sarutobi on the way to the war grounds. Kishimoto wanted to make it clear that was on the level of Sasuke and Naruto and that she suorassed her mentor like they did.
