Totally lost and confused about NameServers

Ok, so I am trying to get my site setup correctly.

I am with the hosting provided Rackspace. I am on their cloud hosting and was provided with the dns' below.

dns1.stabletransit.com 69.20.95.4
dns2.stabletransit.com 65.61.188.4

From my understanding I need to configure my settings in WHM to the provided dns above. Where's is the option located in WHM?

My domain is then registered with godaddy, do I simply setup the nameservers?
Or is there more to it than that?

Our site is currently up our main IP is not resolving to our hostname.

This might help explain more intoDNS: oddfuturetalk.com - check DNS server and mail server health

I appreciate anyone who can point me in the right direction.

 

It does work, but I can access it from certain connections I.E My Phone, Family's House.

And some of my users are reporting not being able to login. I have parked my domains on godaddy and used A to point to my main IP.

We were provided with the 2 stabletransit IP's and we have not set them up or used them?

Maybe its just propagation?
