This is really a question for cc-metadata, followups directed there.

Search engines (Yahoo! and Google's CC search) only work at the page
level so far. You should include a license notice with appropriate link
for each licensed element, but don't expect search engine behavior to be
influenced by this, unless you are able to give each element its own
page (e.g., click a comment title to obtain a page with only that
comment and the license notice for that comment, an image to obtain a
page featuring only that image...).
Soon there will be specifications licensing metadata at a more granular
level than page-only though I expect we'll have experimental support in
our prototype search http://search.creativecommons.org/?engine=nutch
long before the major commercial search engines are interested.
