How do you site page and paragraph numbers?

I use the MLA system of citing. To cite a page # you can do it like this : write your sentence that you have quoted, summarised etc. then put the author's last name followed by the page number in brackets after it. e.g. Okonkwo was deeply grieved (Achebe 129). You can also use the author's last name in a sentence then put the page number in brackets at the end of it. Achebe writes that Okonkwo was deeply grieved (129). To cite a paragraph, you follow the same method but instead of the page number you say: author name or essay name if no title then par. # in brackets. You must cite the full bibliography on a "Works Cited page at the end. We encounter the Igbo people at a watershed moment in their history and culture (Smith par. 1).
