Please help regarding the battery for my new rMBP

Hi everyone. Ive read that it is safe to plug in your macbook all the time and use the battery every 1 week and let and charge it again once it reaches 50-60%. Now Im wondering if it is safe to remove the charger once Ive decided to shut down my computer. And just plug the charger back again before opening it? Will it let my charge cycles go up? Or would you suggest to just keep it plugged in all the time even if it's off. Im actually worried about keeping it plugged in all the time because during in the mornings, my room get's really hot. And Ive also read that the enemy of our batteries is heat. For now, Im gonna uplug it because I'll be at school and Im not gonna use it so Im gonna leave it at home. This is my first mac and my mother gave it as a gift. So I want to keep the laptop and the battery as healty as possible. Thanks!

MacBook Pro with Retina display, OS X Mavericks (10.9.1)

You can leave the charger connected or not. It makes no difference as for the health of the battery.

Originally, I plug in my laptop when the battery reaches 10-15% but Ive read on some forums that its much better to leave it plugged in. So would you suggest to just let it unplug when I decided to turn off my computer? Or it makes no difference?

Charge cycle will not go up.

Plug it in whenever the battery needs to be charged.

At home when Mac is in use, keep it plugged in.

When updating software, make sure that Mac is plugged in.
