Truly, I suggest you send the text as it is now because after the editing process, you’ll likely continue revising it (“polishingâ€ it). 

You actually asked three questions and my three answers are all yes.

1. My  editing includes line by line (the easy part) and structural/organizational/conceptual issues (the harder part).

2.I use the comment function to suggest deletions/additions/clarifications, whatever I think is necessary while reading the text.

3.As I have done thus far, I will answer all of your questions, and the more, the better.
