Cisco PIX and 837

I've just got hold of a pix for my SOHO and wish to instal. Cisco PIX Firewall Version 6.3(4) Cisco PIX Device Manager Version 3.0(3) I cannot connect to the PDM, Java version issue i think so Im stuck with CLI configuration. I have a Cisco 837 that currently gives us intenet and i can see where the PIX fits after reading the Cisco config guide. However I cant seem to get traffic flowing inbound/out when i drop the PIX in place. I'm trying to read up on configuration, Access-lists etc but I getting stuck. Can anyone help? - Pasted config of PIX & 837 below. We have no need for DMZ we only have 5 desktops behind the PIX.
Im not sure where I'm going wrong...
