Help DNS on Win2003

I am new to dns servers. I am currently renting a machine from a host and have full root access to a windows 2003 server. The host gave me this info
> If you need nameservers for this server, you > can use the following:
> ns2.theplanet.com 12.96.160.115
> ns1.theplanet.com 216.234.234.30

I need a step by step walk through on how to setup this info on my new server.

I have URL pointing to the above records but how do I go about resolving it to this machine?
Again thanks for your time and looking forward from some great expert advice.
Is it possible I don't have to use there dns servers and just make my own?
I haven't a clue. I just need one domain name pointing to this box and having technical difficulties.
