Target module with custom layout in Magento

Question

In my custom module, I'd like to include an extra block and style sheet that targets only pages within my custom module. So that when i access myserver.com/configurator/

Pages will use the correct template I specified

In the catalog.xml file, I noticed

<catalog_category_default>

That seems to be what I am looking for, so I tried:

<configurator_default_default>
    <reference name="root">
        <action method="setTemplate"><template>configurator/2columns-right.phtml</template></action>
    </reference>
   <reference name="head">
   <action method="addCss"><stylesheet>css/configurator.css</stylesheet></action>
   </reference>
   <reference name="content">
    <block type="configurator/guide" name="timeline" template="configurator/guide/timeline.phtml" />
    </reference>
</configurator_default_default>

But it doesn't change the template for pages within the module.

I also tried

<configurator_guide_default>

But it doesn't pick up the correct template

If i put it within the specific page such as

<configurator_guide_page1>

Then it works.

Edit:

If someone just has a link to an article explaining how to do this, that would help me out as well. Everything I've read about layouts only shows how to target a specific page or default (all pages in the site).
