You can never ask too many questions about Greek! The only way to wear out your welcome here is being persistently rude or antagonistic (even then people are pretty forgiving).
I don’t have any experience with Athenaze but if you haven’t already seen, there is a recent thread here http://discourse.textkit.com/t/my-journey-through-the-exercises-of-athenaze/17430/1 with someone going through what is (I think) the same edition you have and getting lots of great advice, especially from Aetos. I’m not normally one for content warnings, but you should probably know that the original poster became very ill after starting this thread.
From your recent posts here you seem to be doing brilliantly so keep at it.
