A parenthesis is used in a sentence to indicate that you wish to interrupt your own sentence to include some comment or information that is incidental to the actual point of statement that your sentence is making. This is actually quite similar to the use of commas, which are used to separate different clauses of a sentence so that they don't all run together, but the parenthesis does so with greater emphasis, it sets something apart more forcefully than commas do.
Parentheses are used in a sentence to capture a note relating to the wording of the sentence. Dashes and commas set apart words in a sentence.
Parentheses are the little "(" and ")" marks used to denote something said in an aside. You should enclose this phrase in parentheses.
No, it does not. Parentheses are used to include information that is not essential to the sentence. They can also be used to de-emphasize information. Of course, you can have complete sentences in parentheses, but it is not necessary.
Square brackets are used inside regular parentheses, in a sentence.
Generally, parentheses are used to set apart additional information from the main sentence. This additional information may include statistics, asides to the reader, or explanations of obscure terms.

(If it adds clarity) one may start a sentence with parentheses.
The entire sentence should be in parentheses, however the portion that is, should contain a period outside of the parentheses.
A period would go inside parentheses to finish a complete sentence, but you always need sentence-ending punctuation outside of the parentheses.
No. Typically, you will only put ending punctuation (in this case, a period) if the sentence within the parentheses is a complete sentence.
Parentheses are frequently used in pairs when something is inserted into the middle of a sentence for added information or clarification.
Write your sentence (then your parenthetical). Use the same punctuation inside the parentheses as you would outside of them and end the sentence with an ending punctuation mark (period).
