Edit: Whoops, I got mixed up in who makes which sets and what is included in each. As said in the linked post, the 'Complete Set' is made by Alfred, and the the Sets A and B are made by Hal Leonard.

* cards 1-36 (yellow): Bass Clef; Treble Clef; Bass clef notes Low C through E above Middle C; Treble clef notes A below Middle C through High C.

Edit: Maybe I should go ahead and pick up these cards and fill in any gaps with self-made cards. I'm going with the Hal Leonard sets A and B. I can always fill in any gaps with self-made cards.
I'm in no big hurry on any of this. I would rather take the necesary time to plan well than jump in haphazard.
