Okay I verified that if you have s-off you will be able to get root back on your phone if you run the RUU.
As expected the RUU did unroot my phone but it didn't touch s-off. So I downloaded CWM 3.0.0.8 from dougpiston.com and changed it to PB31IMG.zip (this has to be a flashable zip file to work) and it loaded from hboot no problem. I then downloaded the latest superuser app using ROM Manager, version 2.3.6.3 efgh, older versions will not work, and just flashed it through recovery. Superuser does not need to be renamed update.zip you can just leave the name as is and select let me choose zip from sdcard and it installs just fine.
Took a while for me to get superuser running again as I had an older version and I could only find the newest version in ROM Manager.
****YOU MUST HAVE S-OFF FOR THIS TO WORK*********************
