I appreciate your concern, but I am currently studying for my CCNA, and trying to learn as many Cisco products as I can. To reassure you, the network it is going on is a complete test network, but i have a few people who are my willing test subjects.
This will take any connection on the inside and translate it to the IP address of the outside interface (PAT).
Assuming your cable provider uses DHCP, you'll want to configure your outside address similar to:
ip address outside dhcp setroute retry
"dhcp" obviously gets an address, etc.
"setroute" sets the default route
"retry" by default retry dhcp 4 times and is configurable
As for "port forwarding" I think I've heard that the PIX has that capability but have not tried it. If the outside interface is dependant on dhcp this probably isn't the best way to go. You might want to get some static addresses from your provider. Either way, allowing remote desktop kind of defeats the purpose of the PIX.
