Welcome to the forum, sartman! You've made an *excellent* start to your vaping journey! (I say that because as I type, I'm vaping w/ protank atop a vision spinner, lol!)
My main suggestion is that you get at least one more complete setup to have as a backup and to use while Battery #1 is charging. Also, two or more tanks will let you rotate your juice flavors. Ecigs components aren't immortal and have the annoying habit of breaking down at the most inconvenient times. In fact, my rule of thumb is always to have backups for my backups, cause in my house, things always seem to go blooey in twos and threes.
Other than that, you are good to go! Happy vaping!
PS: There are no dummies here, only new vapers with excellent questions!
