I agree with most of what you wrote, but have a question concerning the "periods and commas always go inside". (Note - I just put it outside of the "'s.)
I thought that the period went outside if the sentence came to an end after the "s and only inside if what was inside the "'s is a sentence unto itself. No???
The period rule is very clear: there is never, ever a time when a period is put outside a quotation mark.

Your observation is valid about the question being in reference to parentheses,(). At first that was my thought, but then I saw the " " marks following "Topic: Parenthesis." Knowing that some people mistakenly call quotation marks "parentheses," and that there is seldom much confusion in punctuating parentheses, I decided the question probably referred to quotation marks and not parentheses.
