What is the point of having Dual Gigabit Ethernet Ports on the MacPro? Haven't full understood that yet. Do they work off each other and double the speed on things? Or is it just for if you had an external hard drive or something?

This is what most folks use dual ethernet for. One for the "light" network, which handles email and web traffic and what-not, then another for the "heavy" network, be it an Xsan server or regular backups or whatever else.On my PC, I use one ethernet port for the internet and local LAN. The other ethernet is for a private network with a backup server, etc.
Did you check your cable? How long is it? Is it coiled? Running near any power cables or fluorescent light fixtures?Sadly, the transfer rates are slower than 802.11g and I can't figure out why!
You can also use it to create a LAN between two machines. I used to do this to fast network my laptop to my Mac Pro, both of which are gigabit and should offer fast data access between machines. Sadly, the transfer rates are slower than 802.11g and I can't figure out why! So, I just wirelessly network them.

Sounds like you may be doing something wrong.
As someone said, use a different subnet. For my computer-computer network, I use 10.0.0.1 and 10.0.0.2 for the computers. My wireless router hands out 192.168.x.x IPs. So I can make sure that if I connect to 10.0.0.2, it will go over the 100mbit connection (my pee cee doesn't have gigabit) rather than the wireless network. If both networks have 192.168 IPs, then you might be going over wireless rather than wired. Different ranges help remove any ambiguity.
Hey All - Thanks for the replies. I'm using a brand new Cat-6 cable (backwards compatible to Cat5/5e). The cable has a clean run from the Mac Pro to my Powerbook. The wireless network uses 10.0.##.## and the wired network uses 192.168.##.##. I'm not sure where to change that (Airport Admin Utility for wireless, but for wired?), but it seems consistent with the suggestions.
To test the speed I'm simply using scp and large file. Is there a better test?
Other suggestions? Others ways to troubleshoot?
Try without using scp (which encrypts/decrypts) the file. Turn the wireless network off, mount the powerbook, and then just either drag a file to the powerbook or cp <filename> /Volumes/<pbook-mount-point>/wherever. The latter won't give you the fancy 0-100% completion bar that scp does nor the speed, but maybe there is an option for that?
