"Enable IPv6 when available". Huh? Wasn't this standard anyway, or is this an option to disable for people who aren't using it? I'm confused, I thought IPv6 was the standard now, could someone clarify on this one?

IPv6 is only being rolled out at certain ISP's around the country. As your ISP requires new hardware which is IPv6 compliant, if you enable this and they aren't, you will have problems.So, enable it if you got it, don't if you don't. You can find out by asking them directly, or Googling for info.

The IPv6 deployment requires a (probably very long, like a decade or more) transition period in which both IPv4 and IPv6 are actively used on the public Internet. The first part, which we're entering now, means essentially everyone having IPv4, but increasing numbers of people having IPv6 too. Because of address space exhaustion it will become impossible to obtain new IPv4 addresses over the next year or two, and increasingly users will have IPv4 only via some nasty proxy, perhaps operated by their ISP. So for those users IPv6 will be faster or more direct when possible.Someone like that will want "Enable IPv6 when available" as will anyone whose job is to test whether IPv6 works properly for customers at an ISP. That's not a bad excuse right? "I'm testing whether IPv6 works properly, not just playing World of Warcraft" ? If you're one of the rare people who already has great IPv6 connectivity and uses the PTR then what are you waiting for? But for most of us, this will either do nothing or make latency a little higher with no benefit for now. It's Blizzard being prepared for the future, that's all.If your PC is correctly configured, checking this box without having IPv6 will do nothing, the Wow client will notice you don't actually have IPv6 yet, and continue using IPv4 hence the phrase "when available".
