You may be able to use template pages in site sculptor to achieve the result you are looking for.
You could add the editable region to the template that is created in the /Templates/ folder to add the side navigation area.
Then use menu writer to create the menu you want to add. I believe you can only add tables to loop on in the menu writer wizard, so you will have to update the recordset on the menu include after it is created. So you can either add it entirely later, or use the ps3_contents table where you want the links to be updated through powerCMS. That will set up a recordset with the correct columns you will use and the correct repeated regions, so that might be the best bet to get started.
Then you will open the menu.php page created update the created recordset (or create a recordset to use with a repeated region if you are doing it manually).
The new SQL statement will look something like:
SELECT C2.ContentGroup, C2.ContentPageSetOrder FROM ps3_contents AS C1 LEFT OUTER JOIN ps3_contents AS C2 ON C2.ContentPagesetParentID = C1.ContentID WHERE C1.ContentGroup = '[YourCMSContentName]' AND C2.ContentPageSetOrder IS NOT NULL GROUP BY C2.ContentPageSetOrder ORDER BY C2.ContentPageSetOrder DESC
That will get you all of the template derived pages in a recordset that you can then use to create the menu links like:
<a href="YourTemplatePage.php?[YourCMSContentName]=<?php echo $row_YourRecordsetName['ContentPageSetOrder']; ?>">
That should be used with the correct opening path to get to the page... it will already be in the repeated region if you use the table looping feature when creating the menu, or you add one now.
