Getting different panel-pages on different level of taxonomy

Hi,
I have a website which is a lot optimized for SEO. What I really would like now, is the possibility to have different templates on different taxonomy depth level.

I have taxonomy_menu working with url_aliassing which is the first step.
I talked to Thomas (http://drupal.org/user/8094) and he advised me to ask in this group!

For my solution I am in the need to extract the terms out of the taxonomy_menu url and show a different panel-page related to the depth of the taxonomy-term.

As you can see I have now the following levels:
Frankijk (France) is url: http://www.wintersport-accommodaties.nl/taxonomy_menu/4/14 (4 = vocabulary)
--Les-Trois-Valleés (5) http://www.wintersport-accommodaties.nl/taxonomy_menu/4/14/45

I would like to show a different panel-page related to the taxonomy-term level.
So "country" panel-page for Frankrijk and "region" panel-page for "Les-Trois-Vallees".

So questions are:
1) How can I get the most right piece of the url out of the url? So 14 for France and 45 for Les Trois Vallees?
I need the terms to work with.
2) How can I show different panels related to the amound of variables behind the "taxonomy_menu" string?
So 4/14 means top level term, 4/14/45 means child level term because of three arguments behind the taxonomy_menu string.
The piece of codes is in settings.php, arg() is not working on this place I think..

I will post back the snippet I build with the answeres on these questions.

Thanks a lot in advance for your remarks!

greetings,
Martijn
