Changing site name and URL

I need to get my old site (Bottles and Beads) changed over to my new site (Exclusive Home Decor - http://www.exclusivehomedecor.com ) - It's listed on
http://dmoz.org/Shopping/Crafts/Multiple_Craft_Artisans/ - I went to "Update URL" and put in the information but I'm not positive that was the correct way to do it. Should I have just submitted my new site - if so, how do I request the old site be removed??
Thanks for your help.

Don't worry, you did the right thing. URL updates generally get processed faster than submissions so, with any luck, someone will get round to it fairly soon.
