I recently switched my main webserver (where I host clients' websites) from apache to nginx and I wrote a custom generic configuration file to handle everything in one place, so domains and subdomains are handled on the fly by creating directories and subdirectories.

Use server_name. Instead of

     if ($host ~* ^(.*)\.(.*\..*)$)  {
         set $sub $1;
         set $domain $2;
     }

you may write in 0.7.x

   server {
         listen 80 default;
         server_name ~^(.*)\.(.*\..*)$;
         set $sub $1;
         set $domain $2;

         ...
   }

As to the redirect:

   server {
         listen 80 default;
         server_name  _;
         rewrite   ^  http://www.$host$request_uri?;
   }

   server {
         listen 80 default;
         server_name  www.*;
         ...
   }
