Re: Q&a - open for every ranks!
Basically the training works like sensei gives an instruction, person performs it and then it continues from there. If you've been skimming through some of the training sessions it should be easy to see how it works. Also it should help that some teachers do train people differently such as yourself explaining things like advantages and disadvantages, or maybe they want you to use the technique in a battle situation. But the general style is just easy, they will explain the jutsu and how it works, and you will perform the jutsu according to how they've explained it. They can also help you out for if you don't completely understand a jutsu.

Senpai can do this as well, but need permission.

As for your second question, it all depends on what you like to use more. I started with Lightning because it's an element I like, but generally it's up to you.
