I can highly recommend Croy's book - although it is very much reading-focused, too. I used it for teaching an online Greek course, and I've left the materials online here. http://www.mythfolklore.net/bibgreek/
I especially like the way Croy presents the Greek verb; it is very sensible, very schematic, and really helps people understand the verb as a system of MEANING rather than just as a big heap of forms.
I would guess, though, that for the kind of full-language experience you are looking for, it is more productive to look at the Attic textbooks that are available. When I taught Greek in the classroom, I used Athenaze, which I thought was truly fabulous - the characters in the little stories are perfect for composition, since students can write their own stories about the characters, turn the stories into little plays, all kinds of good stuff. Since most of the students in the classes I taught actually had as their goal reading the Bible, we would just Athenaze on M-Tu-W-Th and then on Friday we used Croy. The two books were not really in synch exactly, but that worked out fine, since the content of the two books reinforced each other nicely, and the different approaches of the two books combined were able to suit the range of different study skills and preferences of the students in the class.
