How do you keep a retina macbook pro battery healthy?

So I'm trying to figure out the best way to keep my battery as healthy as possible in my retina Macbook Pro because I was recently told at the Genius bar that replacing this battery could cost around $400.

I've read in some places when trying to figure this out that you don't want your laptop plugged in all the time, I've heard newer batteries don't need to be periodically discharged to zero (calibrating batteries like in the older macbook pro's), I've read that you want the electrons in the battery to me moving as often as possible, so you want your computer to be charging and discharging constantly, that you shouldn't have the power cord plugged in if it is full (which would seems to lead to a high number of cycles). Now the Genius I went to today said I should keep my laptop plugged in more often to keep the number of my cycles low. I'm getting a lot of mixed messages and I am a bit confused. Anyone know the definitive way to keep your battery healthy?

Here are my current battery specs. I got my retina macbook pro July of 2012, so i'm at about 16 months w/ this battery
