Windows 8 OEM System Builder

I hope i'm not being really annoying with posting so many questions....
This site, http://support.apple.com/kb/HT5634?viewlocale=en_US&locale=en_US , says for my mac, the MacBook Pro 13-inch, Late 2011 should work for Windows 8, 64 Bit, Windows 7, 64 Bit, and Winodws 7, 32 Bit.
With that in mind, I chose what seems to be the newest, the Windows 8, 64 Bit.

I found this on Amazon and just wanted to make sure this is what i need. is this the full install cd and not just an upgrade? http://www.amazon.com/Windows-System-Builder-OEM-64-Bit/dp/B0094NY3R0/ref=sr_1_1 ?ie=UTF8&qid=1377372064&sr=8-1&keywords=windows+8+64+bit+full

i tried looking, but im not very tech savy, so i just got confused....

If that ones no good, what about Windows 7, 64 Bit? I see so many options on Amazon when I search Windows 7, 64 Bit, any idea what might be best?
