I do mark my lines top, bottom, left, right. My way of keeping it straight in my head that I've hooked things up right. But I've also had a stroke, so patterning things helps keep me straight.
About the lines - Once you've found a method that works - DO IT THE SAME - EVERY TIME!!! Habit, whatever you want to call it, but get used to doing it the same - every time out. I go so far as to never ask or allow some else to wind up for me - if it's messed up, I'm to blame!! But seriously, John's method, once mastered, is darn near foolproof! One of the only differences in our ways, is that I use 2 stakes. That allows me to keep the sets separated as I wind or unwind, with each handle slightly apart.
