2 Problems: Custom Config AND Intern File Browser

I started using FCKeditor today for a website project and it's a very powerful and good to use tool, but I am having some problems with it.

Problem 1 - Custom Config
I checked the forums already for a solution to my problem, too bad the fixes I found don't work. I am using the following code to get info from the database.

<?php
$oFCKeditor = new FCKeditor('content') ;
$oFCKeditor->BasePath = 'fckeditor/' ;
$oFCKeditor->Value = $row_content['omschrijving'] ;
$oFCKeditor->Config["CustomConfigurationsPath"] = "fckeditor/hofstede.js"  ;
$oFCKeditor->ToolbarSet = "Hofstede";
$oFCKeditor->Height = 300;
$oFCKeditor->Create() ;
?>
