Answer 1

In your list settings you'll find "List Fields and *|MERGE|* Tags". You can add here whatever you want !

You can also add "merge vars" programmatically via the api :

• listMergeVarAdd
• listMergeVarDel
• listMergeVarUpdate

When you add a user in this list via listSubscribe, just use the merge vars as you would do with FNAME

$merge_vars = array(
     'FNAME' => $fname,
     'LNAME' => $lname,
     'PHONE' => '010203040506',
     'OTHERCUSTOM' => 'custom field'
);

If you need to update user information, just turn update_existing flag to true.
