Setting up new rig

So I posted earlier that I had a new AW 14 rig coming in and am still waiting for it but it should be arriving pretty soon. I was just wondering what advice you guys had for setting up/configuring the computer. The stats of my rig are in my signature. Also what are some necessary programs you download? This is my first AW laptop and first high end computer overall so I just wanna make sure I don't screw up.
