I think ninjutsu training would still be essential. I mean, the Kote is just a device, scrolls can run out and it can be damaged, malfunction, etc etc etc.

3: obviously not, scrolls are finite.

4: Yes, why not?

5: Why not? Assuming the blood price would be payed when sealing the jutsu.

6: Questionable, it's not clear whether ninjutsu put any strain on the Kote. But as we know from Naruto, it does put a strain on the user.

7: as Konohameru showed, it's not quite the same as using Ninjutsu yourself. e.g. it can not be aimed as well. Every jutsu would also need to be properly programmed beforehand, so mid-jutsu corrections would be impossible. And these corrections (e.g. letting wood structures move) are what make Wood Release strong.
