Minha duvida era "Como vou fazer pra esse css ali desaparecer.. eu nao uso ele!!"..

Entao acabei achando essa saida.. gostei e tah ai pra sempre lembrar.

Coloque esse codigo na funcao seutemplate_preprocess_page no arquivo template.php

<?php
// get all the current css information into an array
$css = drupal_add_css();

// copy stuff you want to keep from these files into your theme's style.css
// or maybe make a separate file for that and @import it into that file

// now we can ditch unwanted core css files from the array and they won't be included
unset($css['all']['module']['modules/user/user.css']);
unset($css['all']['module']['modules/node/node.css']);

// and now, removing the css files of some contributed modules
// I'm putting them into an array to save space and code repetition
$rm[] = drupal_get_path('module','content').'/content.css';
$rm[] = drupal_get_path('module','devel').'/devel.css';
$rm[] = drupal_get_path('module','gotcha').'/gotcha.css';

// now we can remove the contribs from the array
foreach ($rm as $key => $value) {
  unset($css['all']['module'][$value]);
}

// now place the remaining css files back into the template variable for rendering
$vars['styles'] = drupal_get_css($css);
?>
