About the Black Lightning, the tattoo does not give Darui the ability to use Black Lightning, he was taught by the 3rd Raikage, the tattoo itself just signifies that he is able to use it. So I do think he would be able to teach it, it is not a transcription seal just a tattoo. And because he is able to use it would mean that he has had training to do so, in turn he would know the mechanics of the technique and know how to teach it.
