Php – Config assistance with nginx & php5-fpm on ubuntu

I am trying to configure nginx with php-fpm (php v 5.3.5) on ubuntu 11. Both nginx and php5-fpm are set to run as www-data. nginx appears to serve html files but php files are not being served (log files generate a 404 error). php5-fpm is running and listening on the same port that nginx is attempting to connect on (9000). Config files are copied below. Files are located in /var/www (www-data has read/write access to all files within that directory).

How can I go about troubleshooting this issue in order to figure out whether php5-fpm is even properly receiving the request from nginx and whether it is unable to process the request because of incorrect privileges/incorrect config file location.

Any help would be appreciated.

nginx.conf file:

 user www-data;

    worker_processes 4;

    pid /var/run/nginx.pid;

events {
    worker_connections 768;

}

http 

{

    include mime.types;

    sendfile on;

    tcp_nopush on;

    tcp_nodelay on;

    keepalive_timeout 65;

    types_hash_max_size 2048;

    # server_tokens off;

     server_names_hash_bucket_size 64;

    # server_name_in_redirect off;

    include /etc/nginx/mime.types;

    default_type application/octet-stream;


    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    gzip on;
    gzip_disable "msie6";
    gzip_comp_level 2;
    gzip_proxied any;
    gzip_http_version 1.1;
    gzip_buffers 16 8k;
    gzip_types text/plain text/css text/javascript application/json application/x-javascript text/xml application/xml application/xml+rss;
    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

default file in sites (enabled/available) folder:

default

server 

{

    listen   80;

    server_name  localhost;

    access_log  /var/log/nginx/localhost.access.log;

    location / {
        root   /var/www;

        index  index.html index.php;

        try_files $uri $uri/ /index.php?q=$uri&$args;

    }


    location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|xml)$ {

      access_log        off;

      expires           30d;

      root /var/www;

    }



## Disable viewing .htaccess & .htpassword
    location ~ /\.ht {

    }

include php.conf;

}
