Yes, a comma should come after personally. Example:
Personally, I find this website very helpful.
Say the sentence aloud and note whether you naturally pause after the word 'field'. If you do, you need a comma. If you don't, you don't need a comma. Personally I would not put a comma (or, 'Personally, I would not put a comma'). If it's your sentence it's your choice (or, 'If it's your sentence, it's your choice').
Certainly, I can add a comma after the word "said," as requested.
NO YOU DON'T PUT COMMA IN THE WORD THAT BECAUSE IT HAS A QUESTION MARK IN IT,AND THAT QUESTION MARK REPRESENT IT'S OWN FUNCTION.

You can put a comma before or after just about any word if the sentence structure requires it. If the sentence structure does not require it, it may be permissable to use a comma to assist in clarity and avoid confusion. Otherwise, don't use a comma. Have I confused you yet? Using a comma does not depend on the word, it depends on the structure of the sentence.
Yes, a comma is usually placed before the word "or" when joining two independent clauses in a sentence. This is known as the serial comma or Oxford comma.

You put a comma every time you take a breath. You most likely would not put a comma after the word that. To see for yourself, say the sentence aloud and see if you stop to take a breath. Hope this helps!! :)
No, you do not always need to put a comma after the word "so" if it is the first word in a sentence. It depends on the context and flow of the sentence.
