Cleaning up Super Cache install

Three questions:
1. I installed your plug in from WP Admin Panel and noticed the following code in wp-config.php and wanted to see if it should be commented out:
1. in wp-config.php:
A. define('WP_CACHE', true); //Added by WP-Cache Manager
2. in the /wp-content folder I still have two files I believe need to be deleted. Can you confirm please?:
1. wp-cache-config.php
2. advanced-caching.php
3. I had not seen the install directions which I believe request this to be done. Is it OK to comment out the code and to remove the two php files at this point? Or do I need do something else?

Thanks for your help!
