No, of course not. The positioning of any punctuation marks depends on the sense of the entire sentence or phrase, not the presence or absence of particular words.
'I have decided to include your drawings in the display.'
'The agenda that he is preparing is going to include the question of conference fees.'
'She said she would perform a selection of songs, to include some by Schubert and maybe a few by Brahms.'
'I'm looking for a recipe to include chickpeas, as I have some left over.'
No, a comma before "as appropriate" is not necessary. It depends on the context of the sentence and whether it flows better with or without the comma.
No, a comma does not always come before "for instance." It depends on the structure of the sentence. A comma is typically used before "for instance" when it introduces a non-essential or parenthetical element in the sentence.
Not at the beginning of a sentence. As you know is a clausal sentence adverbial, and as such it should generally be set off by punctuation. That would mean a comma after it at the beginning of a sentence, a comma in front of it at the end of a sentence and commas on both ends when it appears in the middle of a sentence: "He is, as you know, rather obstinate."
A comma usually comes before "which" when introducing a nonrestrictive clause in a sentence. If "which" is part of a restrictive clause, then a comma is typically not used.
Quotation marks typically go before or after commas, depending on whether the comma is part of the quoted material. If the comma is part of the quoted material, it goes inside the quotation marks. If the comma is not part of the quoted material, it goes outside the quotation marks.

Sometimes, but not always. There is no one single rule that applies to "but." ----

It depends on the type of sentence. So your answer would be not all the time. I hope that helps! :)
No
A period should come before the footnote at the end of a sentence, while a comma should not.
No, definitely not. In very many cases it would not even be optional. It would simply be wrong.
If a comma is needed, it normally comes after parenthesis.
The comma would come after it.
