Here is some code from bindings.xml mouseOver, with my
interpretations:
Get the meta-object for the graphical rendering object under the
event:
var object = Firebug.getRepObject(event.target);
if (object)
{
Get the type of the meta-object
var rep = Firebug.getRep(object);
Get the Firefox object that the meta-object represents from the type
object:
object = rep.getRealObject(object, FirebugContext);
if (object)
Firebug.Inspector.highlightObject(object,
FirebugContext);
}

Some side panels, like Style, synchronize to the main panel selection.
Others, like the Breakpoints side panel, act like alternative indexes
into the main panel. It sounds like that would be a good model for
you.

I don't know your eventual goal, but another suggestion: the XPath
side panel could be an "editable history". So the side panel would add
one XPath for every selection in the HTML panel. The user creates the
list by selecting HTML elements rather than right click > add; Each
XPath would have a (x) button on the left to remove the XPath. Mouse
over on the XPath item would highlight the corresponding HTML
object.
Novice users will be able to use the XPath side panel immediately
because it will always have content. Expert users will know to clear
the XPath side panel and then select the HTML nodes they want,
deleting any they add by mistake.
