The iRex Download/Docs page has a document called "How to make content for your iLiad" which covers the manifest.xml file and the icon.

Here's my manifest.xml file that I use for one of my PDFs. I usually use this as an example file for creating my other manfest.xml files:

<?xml version="1.0" encoding="utf-8"?>
<package>
    <metadata>
        <dc-metadata>
            <Title>BOFH 1</Title>
            <Description>Bastard Operator From Hell Vol 1</Description>
            <Date>2006-06-25T20:36:52</Date>
            <Format>pdf</Format>
            <Language>eng</Language>
            <Type>book</Type>
        </dc-metadata>
        <y-metadata>
            <FileSize>000</FileSize>
            <ItemSize>000</ItemSize>
            <startpage>BOFH 1.pdf</startpage>
            <version>000</version>
            <image>bofh.png</image>
        </y-metadata>
    </metadata>
<pdf><lastRead>414</lastRead></pdf></package>

The icon is simply the "<image>bofh.png</image>" line in the "<y-metadata>" block.
