I have a similar model - a DocumentTemplateElement has a mm-relation to 
itself to set up a tree structure. I've solved the rendering by using a 
partial that looks like this:

<f:if condition="{element}">
	<f:then>
	<ul>	
		<f:for each="{element.elements}" as="ele">
			<f:render partial="DocumentTemplateElement" arguments="{element: ele}" />
		</f:for>
	</ul>
	</f:then>
	<f:else>
		Error - no element given
	</f:else>
</f:if>

You normally do not need a repository for fetching the childs. You 
access them through the root object. $subblocks = $myblock->getSubblocks();

If you have to fetch them from repository, you may write a special 
query, that checks if the object is associated as uid_foreign in your 
mm-table. Or you add a depth property to your model, that you can ask 
via SQL.
