Q. In MLA format, if I am paraphrasing information do I still need to intext cite the author?

Hello again

You definitely need to include an in-text citation for paraphrased information. Sometimes it can be confusing since you are putting the information into your own words, but since you still got that info from another source, you need to credit the source. In fact, when writing a paper, you should paraphrase more than quote someone directly, as a general rule. Paraphrasing demonstrates that you understand the material and are applying it to your topic. Of course, sometimes direct quotes are most appropriate, so don't be afraid to use them.

If your entire paragraph is paraphrase of info you got from one of your sources, just put the citation at the very end, like you said. You don't have to mention the author or do an in-text citation for every sentence. In this case, I would go ahead and include the author's last name in the (), even if you mentioned them in the text of your paragraph, just to be clear. If you got the information from a section or chapter, use the page or page range. 

Here is an example I edited from Purdue Owl. It's just a single sentence, so we will pretend it is the final sentence of the paragraph: 

He extensively explored the role of emotion in the creative process (Wordsworth 263-268).

MLA requires you include page numbers for books, so definitely include those.
