Below is the code i'm using to display both the products and layered navigation on CMS pages. However, the layered navigation filter isn't being populated by attributes to allow for filtering.

<reference name="content">
        <!-- Layered Navigation Block -->
        <block type="catalog/layer_view" name="catalog.leftnav" template="catalog/layer/view.phtml" >
                <action method="setCategoryId"><category_id>2250</category_id></action>
        </block>
</reference>

<reference name="content">
        <block type="catalog/product_list" name="home" template="catalog/product/list.phtml">
                <!-- Product List View -->
                <action method="setCategoryId"><category_id>2250</category_id></action>
                <block type="catalog/product_list_toolbar" name="product_list_toolbar" template="catalog/product/list/toolbar.phtml">
                        <block type="page/html_pager" name="product_list_toolbar_pager"/>
                </block>
                <action method="setToolbarBlockName"><name>product_list_toolbar</name></action>
        </block>
</reference> 

category, with id equal to '2250', has it's anchor attribute set to 'yes'.
