ASA 5505 initial build - Failed to locate egress interface (Please help :-) )

Question

Hi, I have just purchased a ASA 5505 and have completed the initial setup via the wizard.  I am currently unable to access services on the outside of the ASA. 
The error: 'Failed to locate egress interface for UDP from inside'....  appears when ever my DNS server attempts a lookup. 
I have configured this several times from scratch using the wizard and I am unable to figure out the issue with the NAT / Routing config. 
If I run the packet tracer I get the error: "(no-route) no route to host", however I do have a default route configured so I suspect it maybe my NAT configuration. 
Overview, 192.168.10.0/24 inside the ASA, 192.168.1.0/24 outside the ASA, 192.168.1.1 is the gateway to the internet.  I ideally want the ASA to use PAT to mask the 192.168.10.0/24 network behind the ASAs 192.168.1.0/24 network address but still allow clients to gain internet access. 
Full config follows, screen shots attached, any help would be very gratefully received. 
Result of the command: "sh run"

Just to want to be sure, can you post output from show int ip brie and show route? And try to remove your ACL for testing purpose or at least don't applied it anywhere yet. 
Once done, try do another packet-tracer to 8.8.8.8 using icmp packet instead of UDP paste the whole the output here. Before doing this, add icmp any any outside command on the ASA.
I know this should have anything to do with your issue, because if ACL is the issue then you will see output being denied by ACL on the packet tracer output. Let us know the results.
