Domain name Change

Hi guy & gals,

I’ve recently purchases some web hosting through hostgator, installed WordPress and my theme. After Importing blog posts and fine tuning the theme I purchased a domain name from 1&1. I’ve pointed the domain (buntology.com) to the hosting. Everything’s all good and fine when you go to buntology.com until you click around – you’ll notice the URL switches to the old Hostgator address.

I’ve visited WordPress’s change your URL page but am still unsure as to what exactly I need to do. I’m afraid of breaking something within my database. Any help/direction would be greatly appreciated.
