Can't seem to find the code reference now, but am I correct that even though a 4 wire feeder is run to a detached utility building, a ground rod is still required at the utility building, and the ground wire from the 4 wire feeder, and the ground wire to the new ground rod would go on the same ground bar that is isolated from the neutral bar ? Thanks Steve...

Yes. Any detached structure requires a ground rod. That is any one with a sub-panel.
Your description is also correct.

250.32(A) requires a grounding electrode at the building.If you use a rod electrode and you don't have 25 ohms or less, add one additional electrode as required by 250.56

250.32(B)(1)describes the proper installation arrangement of the EGC and the grounded conductor.(float the neutral)
