okay i have nameservers, now what

By creating name servers, do you mean you have registered them with a valid registrar?. Doesn't look like you are using cPanel from the above description because cPanel does not require manual tasks. Here is what you have to do to get the site running.

1- Register name servers against your VPS IPs at a valid name server registrar.
2- Name service running on your VPS with the two name servers configured.
3- The domain needs to then be pointed to the name servers at domain's registrar.
4- A proper web server like apache running and serving requests for your doamin from a specified folder where you are placing the web files for your domain.

If you are using cPanel, it does automate the process to a great extent.
