The static allows the PIX to answer for these devices. Thus, with this static, the devices on the DMZ would send requests directly to the IP Addresses of the inside. You use an ACL to control what devices and what protocols are allowed to "use" the static that you built.
You will probably need a NAT statement to go from the inside to the outside.
There is a lot of good documentation on Cisco's website regarding static and NAT usage.Hope this helps.
