Thanks for all your hard work. I've been setting up the correct software and getting familiar with it, doing the backups, and going through the guide step-by-step. So far everything is working using the Parallels virtual machine on my MacBook Pro. I'm confident that I can read and write to and from the phone, my big concern is doing the actual flash. Many have warned against flashing on a virtual machine, some have done it successfully. I may wait until I upgrade to the new 10.5 operating system, which includes BootCamp and allows you to boot up in Windows.
