re; cleaning:
I just blow my atomizers out maybe once or twice a day (hold paper towel at one end and blow through other end to get the burned up gunk out. Some people swear you have to soak in vodka or coke or boiling water for 15 minutes, blow out and let dry for 24 hours (done weekly) but none of the manufacturers recommend doing any soaking that I've seen and my atty's work just find with a blow out once in a while.
It's important to keep the thread ends clean on all your parts though (wherever stuff screws together), I always wipe the threads off any time I change atomizers or charge a battery.. basically anytime I unscrew or screw anything on I wipe off all the threads.
Batteries can just be wiped off with a paper towel (the battery is the cigarette body part - not the cigarette filter looking part).
re; storage:
People have different storage solutions, the most popular is probably just a craft box with dividers (like you'd get to store beads or sewing equipment). If you go to Michael's craft store you'll find a pretty good selection there (plus you can pick up some
Wilton's Glycerin while you are there - just in case - it's near the cake decorating stuff).
But if you have kids at home I do recommend you get a
locking box to keep your e-liquid in, just in case anyone gets curious while you're taking a nap or something.

re; the convenience store e-cig is junky:
Many people are satisfied with the convenience store e-cig, but more people find that their performance can be inconsistent and certainly they do not last as long as a quality e-cig like an eGo or a Riva. If yours is not producing vapor right out of the box, I recommend bringing it back and seeing if they will either trade you for a new one or provide some refill carts gratis. It's likely that the cartridges were dried out (ie: old, or not properly packaged). And, no, the kit you got will not be like that.
Good luck!
