Theming a single node.

I've been looking all over to try and figure this one out but haven't found what I'm looking for yet.

The situation.

I have a group of nodes all of a certain content type.
They all belong to different terms and have paths accordingly. ie. sitename/sectionname/termname/title
Except the one landing page which is sitename/sectionname, which is a node of the same type. (It is using the wikitools module and is the main page of the wiki)

This is great except that I need to theme the front page differently than the rest of the content.
Specifically I need to theme how the node is displayed (the rest of the page is fine).
ie. I don't want title, tags, etc to appear.

I also have pathauto installed.

Currently:
page-(sectionname).tpl.php
node-(type).tpl.php
both are working on all content of that type....

I have tried using these below to differentiate:

node-(nid).tpl.php
node-(type)-(nid).tpl.php
node-(sectionname).tpl.php
node-(sectionname)-(nid).tpl.php

page-(sectionname)-(nid).tpl.php
page-(nid).tpl.php

I'm not sure what else to try here...
and am hoping I'm missing something obvious...

any suggestions out there?

a bit more to add....

Themeing based on path. I have this happening all ready, and the node is the root of that path, but I want it to be the exception of how the path is themed, without having to create a deeper path or theming all the sections separately.

ie. siteaname/sectionname/term/ I don't want to become siteaname/sectionname/string/term/
nor do I want to put separate themes for all siteaname/sectionname/term/'s + siteaname/sectionname
