It looks like the dumped roms are a .nbh file, which I think I can use.
But the shipped is exe. Do I put the phone into boot loader mode, connect to my PC and run the exe?
Thanks. I tried looking through this thread, but I am sure I missed the above info.....

The dumped is unsigned, which means it can only be flashed on an unlocked phone. It is just the OS rom. The shipped rom is signed, which means it can be flashed on a locked or unlocked phone. It contains the OS and radio rom and also the PRL and PRI.
The exe file is just a convenient auto opening package file that contains the nbh and the RomUpdateUtility.exe files, along with the other important RUU files. You do the exe file the same way you do the ruu. Just establish usb connection with computer and phone (in activesync or bootloader) and open the exe. If you want the files inside that packaged exe file, you can extract it with winrar.
