CISCO PIX Firewall Configuration

We have a CISCO PIX 501 series firewall/router and we require configuration of the same. Currently this router works in a bridged fashion, with the AT&T Router facing the Internet. Two changes are desired now and in the following four weeks. This is a two step activity. (1) Permit the Static IP's to pass through the Network, as they are blocked now. (2) Reconfigure the router with new parameters after four weeks. (a) The new configuration required would have a new set of Static IP's with new ISP (b) Permit access to our applications and websites that will be made live from our servers (3) Provide documentation of the changes made. This should be a pretty simple configuration change for someone that has worked with CISCO PIX products.
