First....cheers to you for reading this thread and searching.
This is really just a judgement call. If your grades in those classes significantly change your GPA....it may be better to wait. If not, then you may want to submit earlier. Even if you submit early, you won't be complete until your scores are released on 7/19. But at least with transcripts in, you will be complete sooner than waiting about 3-5 weeks at the end of July.
The later you are (especially as a non-traditional student) the less leverage I (personally) think you have. If your GPA is solid, I'd go with be early, and use the good grades in update letters.
