So, the link to the XWing FAQ says 20 FEB 2015, the FAQ itself (still) says 26 SEP 2014. I glanced through it and did not notice any changes between the two. Am I missing something here?

There was a screw up when the website was updated and an out of date FAQ got posted by mistake, so the had to repost the current FAQ which caused the website to change the date the FAQ had been updated.

So again, the "current(correct) FAQ" is dated 26 SEP (supposedly the newest?). Because I see no difference between it, and the one I printed out back in November.

No, the 26 September is the current, and latest FAQ. I was kinda expecting we'd see a new one by now, but it seems FFG are waiting a bit longer so they can collate and incorporate the more common questions from Wave VI after a bit more playtesting from the community.

One thing I'd love to see in the new FAQ is clarification about Autothrusters, arcs, and secondary arcs. There are so many discussions, and none of them come to clear definitive conclusion.

I think this is actually pretty well covered, between the entries on the Firespray, Backstabber, and Outmaneuver. I'm not sure what else they could add that isn't already in there.
