It might not be able to resolve domain names. Can you ping an outside  
IP address?
Try visiting sites by their IP, does http://64.233.167.99/ work? (one  
of Google's IPs)

What is inside your /etc/resolv.conf?
Try putting the following in your /etc/resolv.conf:

	nameserver 208.67.222.222
	nameserver 208.67.220.220

and see if it makes a difference.

looks like route is missing a gateway, u should have another line  
there like this:

default	192.168.0.1	255.255.255.0	UG	0	0	0	eth0


make sure your /etc/network/interfaces has only this for eth0:

	allow-hotplug eth0
	iface eth0 inet dhcp
