>> What other marketing material (articles, banners, etc.) will be needed by JV and affiliates in order to market it to their:
review articles
a series of promo emails they can add to autoresponder
thank you page graphical banner
standard variety of banners (namely 125x125 button banners)
exit pop window they can add to their pages
short text ads for text links, facebook statuses, tweets, signatures
rebrandable PDF
videos (you walking someone through the contents of a physical copy of the same book?)


But typically a couple of graphics, a couple of emails/articles and a couple of short text ads is enough to get you started quite well.
