Your config looks OK, What is the error message your seeing when trying to browse the internet? Do you have LAN router with the PIX in the middle and a internet router in front, i.e. LAN-ROUTER-PIX-ROUTER-INTERNET. Also, try command 'clear xlate' and try again.
Pinging from the inside will only work if you create an access-list on the outside interface for the response traffic! (have to remember that ICMP is not statefull inspected)
If all this works it could be the case that only name-resolving is not working, this is easy tyo determine by browsing to http://www.cisco.com (if this works not, but it works with the IP-address, you're having problems with name resolving
Hope this helps. Please keep us posted on how things are going.
