All taken from the Letter from the Producer, XXVI
Job Exclusive Weapons: Were never mentioned to be in 1.22a or 1.22b though from the sound of it 1.22b is more likely.
Imperial Stronghold: Same as JE Weapons, it was never specifically mentioned for patch 1.22a or 1.22b or 1.23 even.
New Imperial Weaponry: Is already in the game. It refers to the Magitek enemies you fight in the new company quests.
Job Balance Adjustments: Were mentioned to be in 1.22b.
Battle Log Revisions: Not sure about this one.

What we know 100% will be in 1.22a

I don't think anything else was specifically mentioned to be in 1.22a; and most was hinted at for 1.22b. (If you think about it with Golden Week, not too much work was probably done between 1.22 and 1.22a) so 1.22a should be smaller I'd think than 1.22b.
