again, TC has beaten me to it and answered pretty much as I would have.
For clarity Ill break this down a little for you:
1) Use less of the wire, as TC has said, by using fewer wraps or thinner wick (Less wraps is better as you want to maintain as much wick as possible)
2) Yes, more coils = higher resistance(more ohms) and tighter wraps will give lower ohms (and possibly strangle your wick, and prevent the needed juice reaching your coils)
3) No, not at all, you just need more practice
I will also add that another way to lower resistance, is to build the same coil with thicker wire. One way to think of it is water pressure, the thinner the pipe, the higher the pressure, the wider the lower, the same applies to electrical current in wire.
Resistance is just that, the resistance of a given material to the flow of electrons - the thicker and shorter the wire (coil) the lower the resistance - the thinner and longer gives higher.
Kanthal is also a higher resistance than nichrome, so for example two coils of the same diameter, one nichrome, the other kanthal, the kanthal will be higher.
