Battery cycles for rMBP and recharges? So I got my first Apple laptop, a Retina MacBook Pro.

I heard that its best to let the laptop discharge until 0% in order to restart the battery cycle or something like that. However I know that lithium batteries have no memory effect and the only thing I would be restarting is the time estimator that shows how much time is left for use.


I may be wrong so I want expert advice from you guys here, do I need to do anything regarding charging my laptop? 
Also, how much time am I supposed to expect when surfing the web, you tubing, Facebook, occasional Photoshop, Dropbox, etc.?
I think the best advice can be given by Apple:

In a nutshell, don't store it at extreme temperatures, store it at 50% charge if it'll be off for a long time, use it occasionally (don't leave it plugged into the wall 24/7/365), or at the very least do a complete discharge every month or two, is my understanding of how best to treat it.

As to expected life, I'm seeing about 6 hours realistically on my MBPr (2.6GHz), with the screen brightness at something I can actually see.
