Question on punctuation

In the following three sentences are they punctuated correctly? Thanks for any help you can give me.


1. After he began the meeting he said " I am not staying."

(Should there be a comma after said? Should the period be inside of the quotation mark?)


2. Have you ever read the article entitled, "English for Careers"?

(Should there be a comma after entitled and should the question mark be inside of the quotation mark?)

3. Carley Simons wanted her death to be remembered; therefore, she staged a pagent.

(Should there be a semicolon after remembered and a comma after therefore?)

Thanks alot!!
