howdy! and welcome!
this is a great place to ask questions and learn
couple of quick things - make sure you have an ohm meter (can pick them up from a number of places in the $10-20 range) for confirming/ checking resistance on build (some folks advocate just using a regulated mod to check, personally, I like to double check on an ohm meter)
check out steam-engine.org (great site/ page for plugging in numbers to give you an idea of what size/ wire/ wraps you will need to get desired resistance - it will likely freak you out a little at first (it did me - HOLY SHIT THAT'S A LOT OF NUMBERS - but again, ask questions
) I tend to keep it simple there - select wire type I am using and gauge, single or dual coil, resistance I am shooting for and diameter (which will depend a lot on what you are building on) - then look at results and tweak as needed)
