You can use Tiles attributes even as simple value holders. In your case,
think about having a list of scripts to load. In your template page do:

<snip>
<tiles:importAttribute name="scripts" />
<c:forEach var="scriptAttribute" items="${scripts}" />
  <script src="${scriptAttribute.value}" type="text/javascript"></**script>
</c:forEach>
</snip>

And in your definition:

<definition name="...">
  <put-list-attribute>
    <add-attribute value="script1.js" />
    <add-attribute value="script2.js" />
  </put-list-attribute>
</definition>

See more here:
http://tiles.apache.org/2.2/framework/tutorial/advanced/list-attributes.html
About the id of the body, it is even simpler, simply use an attribute of
type "string" and import it in your layout page with
<tiles:importAttribute> and use it as a normal bean in page scope.

On 3 above I'd like to change the class attribute on list items based on

You can apply the same suggestions I gave you above. Moreover, you might be
interested in the View Preparer:
