simulating "freeze transform" feature of 3D apps in AE?

You could add a new null. Hold shift while parenting the new null to the old null (this is new in Ae CS6) -- this will copy the transforms from the original null to the new null. (Pre-CS6, copy and paste PSR.)

Now unparent the new null, then parent the old null to the new null.

Your original null will now have zeroed-out transforms because they are measured locally relative to the new null, which had matching transforms in world space.
