Yes. You must obtain permission for any poem or lyric not in the public domain. Sometimes, the works of deceased poets (e.g., T. S. Eliot) are protected by the poet’s estate, even if those works are old enough to be in the public domain. Any quoted material from a book not in the public domain requires permission from the copyright holder to be used in your book. Unless you have permission to use a specified image, you will not be able to include it in your book. If you are using an image under a Creative Commons agreement, a notice specifying that must be included in either the front matter of your book or in the caption for that image.
