I used the guide at http://forum.xda-developers.com/showthread.php?t=285435 to upgrade my Wizard, like you I started from rev. 1 so skipped the downgrade sections prior to the unlocking CID steps. If required to unlock CID, Mestrini's tool at http://forum.xda-developers.com/showthread.php?t=329170 will do this with simplified steps. At step 17 choose your ROM of choice with the desired IPL/SPL and radio ROM. The T-Mobile ROM listed will also replace your OS.

If you are just going from stock to stock...just flash a 2.xx rom. I had a stock rom with a different radio, never unlocked my Wizard until I actually wanted to flash a non-stock rom.
