How to format heading/page number on Word 2003 for MLA style?

I am taking College Composition and need to format my papers on MLA style on Word (I have Office 2003 version). I got the margins and 2” spacing between lines. The only thing I cannot get right is the heading and page number. I tried separating the heading from page number, and it didn’t work. So I put them together on the same heading and the heading appears on all pages with the page numbers, and I don’t want that. Can anyone help me with this? If you give me step by step I would appreciate it. Thanks a lot!!
