What to focus on?

I had put this in help and support, however I seem to have posted in the wrong place, so I'll re post here.

Hello everyone, I'm Giatsulore. I've been playing League off and on for a while now, am currently lvl 17, and somewhat hoping to go pro. I do have a team in the making, however, all the potential members are very low level at the moment(The lowest level being around lvl 6, the Highest being myself).

So the question I have is, should I focus on teaching the other members of my team the basics, and what I know so far, and we all learn the rest as a team, or should I be focusing on getting to level 30 for ranked matching, so I can teach them even more?

I personally have a decent understanding of the game, I know how to teach others, but the problem is, when teaching myself, I fall short. I watch videos of others playing, and I can sometimes see how they do things, but then I get into a match, and try to replicate it, with very little success. I'm decently knowledgeable with many different items, however still do not know all the items, normally just sticking to a build, and rarely branching from it. I know the summoner spells, no help needed there.

And can anyone give me pointers on how to teach my team not to just stand idlely in lane (I've told them many times to click around to make it harder to get hit, but I'm not sure they understand what I'm saying, even though I've shown them what It looks like when they do it right)
