Anyone know how to get this to go away from the App store? I've done the update a few times and it keeps appearing in my software update list.

I'm a rolling stone.
Oh, wow. I didn't know that. Sigh. I'm a damn noob!

The reason is, if you were low on battery and start the install and then the Mac runs out of juice while updating it will get you an unbootable Mac.
It is firmware, firmware controls your Mac Hardware, with a corrupt firmware you have a brick, so Apple does a good job on this, as most others.

I figured it wouldn't let me update if it recognized it was low enough on battery (sub 25%). Not sure how a 30 second install could drain any battery fast enough, but I guess it's a nice safe measure.

isn't there another quirk that allegedly each end of the thunderbolt cable needs to be updated (each end has a separate mote-pc is how I understood it) I dunno as I haven't tried updating my TB cable yet?

No. This update can be applied without a cable being attached, and there is no mention of needing to connect a cable.
