Need Urgent help with MLA Citation Questions

I have an assignment to research "Why did the US intervene in Somalia in 1992". I really need a good grade on this and have worked upwards of 18 hours on the content, so it is solid. A large part of the rubric is correct MLA citations. I have a couple of questions that I hope someone can answer for me.

1) I have a online brochure as well as a case study, that I am fairly sure were originally published as an actual brochure, but the online version does not have information about original publication. The bibliography tool I am using (EasyBib) asks the question about original publication, so I assume this is important. I'll provide the links for these below. Do I cite these as online sources only since I don't have original publication information?

2) Also, I have several online magazine articles from Time, Newsweek etc.... Obviously these were originally published as hardcopy. But I have no page numbers with the online version, nor do they provide publication and issue information. How should I handle this?

Thanks so much in advance for your help. I have to get this paper completed by midnight tomorrow.
