How about this:

$attributes = Mage::getSingleton('eav/config')
    ->getEntityType(Mage_Catalog_Model_Product::ENTITY)
    ->getAttributeCollection()
    ->addFieldToFilter('source_model', array('notnull' => true))
    ->addSetInfo();

foreach ($attributes as $attribute)
{
    echo "{$attribute->getFrontendLabel()}:\n";
    foreach ($attribute->getSource()->getAllOptions() as $option)
    {
        echo "  {$option['label']}\n";
    }
    echo "\n";
}

By using the eav/config and eav/entity_type chances are you will be reusing an already loaded collection, which of course is more efficient then reloading the same data in new collections.

EDIT: Updated the answer to include the attribute collection filter suggested by Aleksandr Ryabov.
