Not necessarily.
I do not use a comma before and after that word, therefore you will not see it in any sentence I have written.
comma in front of therefore; semi colon in back of therefore
No. Example: "It can therefore be declared that ancestors of modern alligators were present during the time of the dinosaurs."
"Therefore" is a transitional word and traditionally a comma is placed after the word to indicate the transition. For example: The economy of the United States was historically based upon agriculture; therefore, a proposed tariff on exported cotton was extremely unpopular with Congress.
You would put the comma before the therefore. for example: I am a girl, therefore I wear make-up and have long hair. (Just an example not all girls wear make-up and have long hair.)

yes
Say your sentence aloud. If you find you pause before the word 'therefore', you will probably want to insert a comma. If you do not pause, no comma is required. Use a comma when the sense requires it, not because you have a specific word in your sentence.

After Example: Therefore, the restaurant was terrible.

No comma is required in the sentence 'Everybody eats ice cream.' Say it aloud: there is no pause, therefore no comma.
Either a comma or a semi colon can be used, depending on the rest of the sentence.

Yes. Therefore is usually used at the start of a sentence, to indicate a concluding idea or thought. The comma following it is used as a pause, separating the connecting word from the idea or thought. Strangely enough, a comma is not used in my sentence above because " Therefore " is used as the subject of the verb is, rather than used as a connecting word to a previous idea or statement.
