Stretchy, don't sweat it, it SEEMS much more involved than it is. I'll try to be short here. All of the ohms, watts, etc. can seem daunting, but it's not all that important.
YES there are "cloud chasers" out there that only care about BIG clouds, run super high wattages to get that. That does NOT mean everyone who rebuilds, or even sub-ohms has to. As your wattage increases typically your vapor production does as well. For me, the WHOLE reason for going to a rebuildable was to be FREE of cartos, cartridges, atomizers, etc. I wanted something where all I had to do was buy a big spool of simple wire, and mega bag of cotton, and just do it on the CHEAP, and I am.
Now onto the ohms thing. Typically the bigger the wire the smaller the resistance, and vice versa. I use 24 gauge Kanthal and make two coils (one for each side) and combined they come out to .35 ohms (yes, that's technically sub ohm). I could use different wire, and make it over 1 ohm if I wanted to. I don't really care about how low I can go, I just found a nice easy wire to use that lasts quite a while, wrapped coils and found that 7 wraps fit nicely into my build deck and just do the same thing every time I re do them. The fact that they happen to come out to .35 ohms doesn't really matter, that's just what they are. If you watch the video above she's using the same Coil Master "coil jig" that I am, and it's SUPER easy. Wrap wrap wrap, put one end in each hole (repeat for other coil) tighten "grub screws" allen wrench screw, trim ends, stuff cotton in, fill with juice and go. Super easy.
I didn't really have anyone helping me, so I bought some bad things, tossed them, and have now found (for me) an easy, very cheap, great tasting solution. The wire and cotton is soo cheap it's rediculous. No more worrying about what cartridge/carto/atomizer I was running out of, and what device it was for, just ONE stack of wire, and ONE stack of cotton, super easy.
The ONLY thing I can think of that IS important regarding ANY device you rebuild is the ohms, BUT only to make sure your mod (battery box) will support it. I'm at .35 ohms, if my El Cheapo eLeaf iStick 30W only goes down to .75 ohms, it won't fire my device. So all you have to do is make sure your mod is rated to go down to whatever ohms you're using, that's it.
Assuming, of course, that said winery pays the required fee. 
They can ship up to 36 cases per year to an individual. If a case holds 24 bottles, that would be about 2 1/2 bottles a day per year!
