Deleeted

I bought a domain at namecheap.com. I didn't know that those 2 addresses that started with dns1./dns2 were all i needed to enter. Also, if the domain i puchased is diffrent from the domain in the welcome email, will it work?

I bought a webhosting package about 2 months ago and i have not been able to figure out how to get a domain name!! Right now i can only access my site via IP address, could someone please tell me what i have to do to be able to access my site using my domain name.
