I don't think you asked enough questions.
I wish this thread would be deleted, because 174 is far out-dated and even 178 is not interesting at all.
Voodoo's OTA Rootkeeper is in my Droid RAZR Utility as well as the Android Market. Googling is an amazing thing sometimes.
Voodoo does as its name says, lets you keep root after OTA updates. Disabling safestrap may not be enough, because you can only update when you have a clean preinstall folder, which safestrap destroys. If you don't have Safestrap you are fine installing any OTA unless you deleting bloat
