Fahrenheit 451 Allusion Thesis/Essay?

I need help making a reasonable thesis for my English cl. I need to write an essay about the book Fahrenheit 451 that has an allusion to The Little Black Sambo. I need to know why Ray Bradbury is alluding to this. Can you please help me format my essay in a MLA or APA style format. I have no idea what those styles are. Please give me some sort of information.
