Who are we kidding when we talk about the "standards" of nano/micro/macro...we're making this stuff up as we go along. 
I didn't see this mentioned, so thought I'd mention it in regards to dual coils. The thing to remember is that when you run dual, your resistance of both coils is cut in half. If you run quad (ridiculous on a Kayfun, of course), it would be divided by four. So, when you want to dive into dual coil, just remember that your resistance of each coil has to be around twice what you want to end up at. (e.g. for a 1 ohm coil, you'd wrap 2 2-ohm coils.) But I agree, stick with one coil for now...maybe try out duals on a RDA, which will be a bit easier on you.
As for some other tips I might throw in, I've found 28GA to last quite a bit longer on my RDA's than thinner gauge. I've found I prefer "micro-coils" myself, usually over cotton which is a bit easier to replace than silica...and I find it tastes a wee-bit better. (I operate on the concept that micro is fairly small and touching.) If you're running an APV, you probably want to aim for 1.2ohm or above. Lower ohms will produce more vapor, more quickly...but there's absolutely nothing wrong with higher resistance coils. Other than that, watch a few build videos to see some different methods...then just pick one and go with it! Once you have things down, play with things and you'll learn like the rest of us are doing!
Anyway, I just wanted to congratulate you on your Russian. I started rocking a Kayfun last week and have been loving it so far. I moved up from the RDA world 'cause I'm running into some juices these days that I want more, more more of...and these tanks are absolutely awesome for that!
