I can get the title of the active menu using
$menu = &Jsite::getMenu(); $menuname = $menu->getActive()->title;
But how can I access it's parent title?

The method getActive return a object with the active menu properties including the parent_id. The JMenu class has a method getItem($id), where $id is a menu id. This method return the same type of object that getActive. So, you can do something like this:
$menu = JFactory::getApplication()->getMenu(); $parent_id = $menu->getActive()->parent_id; $parent_title = $menu->getItem($parent_id)->title;
Since you can get the active menu, you can get the rest by getting the
tree. This is usefull to traverse the item list, not just the parent!
So that you understand better, I'm spliting the answer in parts:
1. Create a variable for the active menu (for simplicity and portability):
$menu = &JSite::getMenu(); $active = $menu->getActive();
2. Pick the previous/parent menu by getting the previous item in the tree:
$parent_item_id = $active->tree[count($active->tree) - 2];
tree is an array, and starts with zero, that's why I am subtracting by 2.
3. Finally get the menu title:
Mind you that you also need to add some checks to see if there is an active menu, and/or other error checks.
