1. It's basically an over-charged version of Naruto's talent in kinesthetic learning. Naruto originally could master anything he could get a feel for, and basically with this he now he has a "feel" for everything. So the basic concept is that Naruto to greatly attached to concept of universe and nature and thus can comprehend, perform, and alter subject matter with ease. Basically, he understands instinctively how the energy of the body works and can alter that energy to restore life force and small body parts with Yin-Yang Release. This is why he is so good at Yin-Yang Release, because he understands principles of life, so he can make great use of an ability that turns images into reality, which is what Yin-Yang Release is. The only real problem is that this talent can't be put into words, and just because he understands it, doesn't mean he can explain it. As for Jigen, the reason it doesn't work like that, in that Naruto needs to "feel" the concept himself, similar to how he can't just learn jutsu by watching or hearing, he needs to understand it on a physical level. But once he does, the mastery is instant. While the rods should indeed not have been a surprise because of his high-grade sensing, Space-Time Ninjutsu warps space and time so its probably harder to defend against "sense wise". This is consistent with the Naruto Gaiden side-story where Naruto couldn't stop the space-time ninjutsu that sucked away Shin Uchiha (Clone) and Sakura Haruno on different occasions.

2. The weird thing about Truth-Seeking Balls is that they never reappear after they are removed or destroyed. And this is consistent with both Obito, Madara, and Naruto. So, it's actually more consistent for them not to reappear than for them to be able to. I suspect that "unlocking" the ability may cause them to appear "subconsciously" but in reality, you need to form them manually, which requires more skill if they are destroyed. Basically, the reason they don't reappear and because the owners haven't figured out how to create them themselves yet.
