I'm in a similar situation and just wanted to make sure I haven't missed something...

I'm a 57 BRD and currently missing Wanderer's Minuet. The guide linked in this thread suggests that I'll get it from The Stiff and the Spent which is my 52 BRD quest... But I don't seem to have that available yet, and the quest-giver appears to be located in Ishgard - which I do not yet have access to.

Looking at another guide... It looks like I need to complete all of the Seventh Astral Era quests before I can get to Ishgard. Does this sound right?
