As far as I remember, Obito said that he could SENSE the Chakra building up in Sasuke's eye. And Nagatowas like: this feeling.... Amaterasu. It is clear that they didn't use there eyes to know that.

Sage Mode grants its user the ability to feel danger, that is by feeling anything that enter the Natural Energy that surround the body. Kabuto did evade Susanoo's arrow by this method, Naruto could do the same as he demonstrated against the Third Raikage. And what do you mean Naruto cannot react to the arrow? that where Sage Mode butt in. And Sasuke would predict Naruto's movement and then fire the arrow. The Sharingan doesn't give such power.

About Juugo, I just meant that borrowing Senjutsu is different that making it yourself.
