Hi Aaron,
the bulletin board application does this on topic pages:
http://extensions.xwiki.org/xwiki/bin/view/Extension/Bulletin+Board+Application#HTopics
You can download it, install it locally and look at its code to see how it's
done.
In any case, you can definitely have several objects on the page. You can
also edit your code as such in order to get each individual object and then
act on it:
#foreach($entry in $doc.getObjects("XWiki.EntryClass"))
#set($entryObj = $doc.getObject($entry))
$entry.prop1
$entry.prop2
#end
Hope this helps,
Guillaume
