Even if you aren't interested in it directly, it's a great first text. Then there's the obvious extra reading in the Italian Athenaze (with recordings from Ranieri), Reading Greek, and Lingua Graeca per se Illustrata. Then add the easier texts - Xenophon with a recording from Bedwere, Plato with (admittedly less good) recording from Toimin, and it's nothing like a plunge into Melville or any other high-register English author.
I do remember about the New Testament - it's in my music library:)
For self-learners the situation is definitely better in comparison to 10 years ago, not to mention 50.
We have more sources now, yet they are still quite limited. The fact that you enumerated all the sources and there's nothing new for me here, perfectly illustrates the current state of affairs.
I have my own idiosyncratic interests in Latin and Greek and, sadly, textbooks and all other learning materials don't address them directly. I definitely see a positive trend, so I hope that by the time I retire I will have an impressive collection of learning materials and plenty of time for Classical languages
