Wordpress site: How to switch from temp address to domain name

Hi Support,

I've changed my A Record to point to my domain awaake.com; that's all working, see http://http://awaake.com/

Awaake.com now points to:
http://ecbiz129.inmotionhosting.com/

Here's the temp URL:
http://ecbiz129.inmotionhosting.com/~awaake5/

What are the steps to take to display the temp url data on awaake.com?

I tried to modifiy the wp-config.php file changing these to awaake.com:
define('WP_HOME','http://ecbiz129.inmotionhosting.com/~awaake5/');
define('WP_SITEURL','http://ecbiz129.inmotionhosting.com/~awaake5/');

Changed url to awaake.com but then I still get the inmotion overview page.

Any ideas what I'm missing?

Thanks in advance!
