Thank you for any and all additional help/good advice, everybody.
So would you think that after working through an Attic textbook and an easier text or two (e.g. Anabasis and The Apology) that a Homeric textbook is necessary for anything other than reference in order for the student to start reading Homer?
Most annotated texts of Homer aimed at beginners will include a brief introduction explaining the Homeric language and the differences from Attic, and the notes will typically explain the forms that are likely to cause problems. After learning Attic Greek, it’s not necessary, in order to read Homer, to work through another textbook specifically dedicated to Homeric Greek. Just plunge right in.
For anyone intending to read more than just a book or two, I would recommend acquiring Cunliffe’s Lexicon of the Homeric Language, available soft covers.
