My Site is not working

I have a problem with my VPS setup. My main site is setup and now I have all the files placed in there but couldn't open the site. One thing I noticed awakrdly is when I do the

host miramichionline.com

It gives me an IP which is not the IP of the name servers(ns1.spry.com and ns2.spry.com).

Do we need to have the NS and A records with the same IP address for the site to work properly?

You need to point the A-records for your domain-name towards the webserver-IP that is hosting the site. Nameservers should also be configured, but since almost every domain-hoster comes with nameservers pre-installed, I doubt that that is the problem.

Maybe you can check what you get when you manually override the DNS-servers. http://en.wikipedia.org/wiki/Hosts_(file)
