Here's an example of the metadata.opf I use to create my epub and mobi books:

<?xml version="1.0" encoding="UTF-8"?>
<package xmlns="http://www.idpf.org/2007/opf" version="2.0" unique-identifier="bookid">
    <metadata xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:opf="http://www.idpf.org/2007/opf">
        <dc:identifier id="bookid">[Book ID]</dc:identifier>
        <dc:title>[Book Title]</dc:title>
        <dc:creator opf:file-as="[Author]" opf:role="aut">[Author]</dc:creator>
        <dc:creator opf:file-as="[Author 2]" opf:role="aut">[Author]</dc:creator>
        <dc:language>en</dc:language>
        <dc:subject>[subject]</dc:subject>
        <meta name="cover" content="cover" />
    </metadata>
    <manifest>
        <item id="ncx" href="toc.ncx" media-type="application/x-dtbncx+xml"/>
        <item id="stylesheetMain" href="content/styles/main.css" media-type="text/css" />
        <item id="stylesheetTOC" href="content/styles/toc.css" media-type="text/css" />

        <item id="cover" href="content/images/cover.jpg" media-type="image/jpeg" />
        <item id="html-cover" href="content/cover.html" media-type="application/xhtml+xml" />

        <item id="titlepage" href="content/title.html" media-type="application/xhtml+xml" />
        <item id="toc" href="content/toc.html" media-type="application/xhtml+xml"/>
        <item id="text" href="content/text.html" media-type="application/xhtml+xml" />

        <item id="image_1" href="content/images/[image-name].jpg" media-type="image/jpeg" />
    </manifest>
    <spine toc="ncx">
        <itemref idref="html-cover" linear="no" />
        <itemref idref="titlepage" />
        <itemref idref="toc" />
        <itemref idref="text" />
    </spine>
    <guide>
        <reference type="cover" title="Cover Image" href="content/cover.html" />
        <reference type="title-page" title="Title page" href="content/title.html"/>
        <reference type="toc" title="Table of Contents" href="content/toc.html" />
    </guide>
</package>

Now, your XHTML files go to the "<manifest>" part. (<item id="titlepage" href="content/title.html" media-type="application/xhtml+xml" /> for example).

The HREF is the location of the file, relative to where you put the .OPF file. Id must be unique.

The <spine> is where you add them all together, in order. Actually the same as a real paper (or leather or any other material!) spine works. I'm not sure if epub uses the <guide>, but that's what you'll see in mobipocket books.

And XHTML is the same as HTML.

I do appreciate the help.
So in the <manifest> part I would need to list all 390 xhtml files?
