No, you never italicize the name of the author, and you only italicize the title of the work if it is a book. If you are referring to a short story you put the title of the story in quotes. This is what you should do if your essay is about Alice Munro's story "Boys and Girls." (Notice that the period at the end of the sentence comes inside the closing quotation mark.) Titles of poems and essays and other short pieces are also put in quotes. Titles of plays are customarily italicized. You can see in the reference link below how Alice Munro's "Boys and Girls" is set off in quotes.
The summary section (often misleadingly called a “conclusion”) is a short recap of what you have said in the essay. You might want to provide a slightly different version of your thesis statement as the first sentence of this paragraph and then provide a few sentences that sum up what the body section said in support of the thesis statement. The summary section should be only one paragraph long for a short paper, but can be longer for longer papers. (Some instructors, like me, even think that summary sections are unnecessary for short papers.)
