Answer 1

Let's say you have an attribute with code some_code.
Here is how you can check if it's a system attribute or if it's a custom one.

$attribute = Mage::getModel('eav/config')->getAttribute('catalog_product', 'some_code');
if ($attribute->getIsUserDefined()) {
    //then you created the attribute
}
else {
   //then it's a system attribute
}

Use the magento soap/rest api for creating a custom attribute for Product and update with values as well,

  $proxy = new SoapClient('http://magentohost/api/soap/?wsdl');
  $sessionId = $proxy->login('apiUser', 'apiKey');

 echo "<pre>";
// Create new attribute
 $attributeToCreate = array(
"attribute_code" => "new_attribute",
"scope" => "store",
"frontend_input" => "select",
"is_unique" => 0,
"is_required" => 0,
"is_configurable" => 0,
"is_searchable" => 0,
"is_visible_in_advanced_search" => 0,
"used_in_product_listing" => 0,
"additional_fields" => array(
    "is_filterable" => 1,
    "is_filterable_in_search" => 1,
    "position" => 1,
    "used_for_sort_by" => 1
     ),
"frontend_label" => array(
    array( "store_id" => 0,"label" => "A new attribute" )
     )
   );

$attributeId = $proxy->call($sessionId,"product_attribute.create",
    array(
           $attributeToCreate
      )
    );

 // Update attribute
$attributeToUpdate = array(
"scope" => "global",
"is_unique" => 1,
"is_required" => 1,
"is_configurable" => 1,
"is_searchable" => 1,
"is_visible_in_advanced_search" => 0,
"used_in_product_listing" => 0,
"additional_fields" => array(
    "is_filterable" => 01,
    "is_filterable_in_search" => 0,
    "position" => 2,
    "used_for_sort_by" => 0
),
"frontend_label" => array(
    array(
        "store_id" => 0,
        "label" => "A Test Attribute"
    )
  )
);
$proxy->call(
 $sessionId,
 "product_attribute.update",
array(
     "new_attribute",
     $attributeToUpdate
  )
 );

I hope this will solve your problem..

You can use Magento default API to get default product list

For more details you can refer to following url:

http://www.magentocommerce.com/api/soap/catalog/catalogProduct/catalog_product.listOfAdditionalAttributes.html

Code used will be:

$proxy    =    new SoapClient('localhost/api/soap/?wsdl');
$sessionId    =    $proxy->login('apiUser', 'apiKey');
$listAttributes    =    $proxy->call($sessionId, 'product.listOfAdditionalAttributes', array( 'simple', 13 ));
