I hope that is all there is in the way of damage.
Measuring the bearing journal is important, you want to check for both OD and roundness.
If the bearing spun it would have been lodged in the connecting rod in a way other than the way it is supposed to be installed. There would be signs of wear or damage on the backside of the bearing shell.

I noticed that my rod bearings do not have a groove, but the ones on your page do. Is that an important feature?
Only main bearings have grooves, rod bearings don't

My plan is to check the chamfer on the crank oil holes, replace the bearings, and install the Kevko pan.
Keep the work you do to a minimum while the crank is still in the motor, you don't want to grind on the crank or anything because the debris will get into the motor. Just make sure the rod bearing journal is still round and the OD is still ok. If the journal's surface finish needs work, take pictures and let us have a look-see.

Will this be adequate insurance against another problem like this?
No ... the motor needs 16 lifter bore bushings, 5 cam bearing restrictions, restricted push-rods and a good oil pan. The fact the damage happened to journal #2 and was not random or universal tells me this is classic Cleveland oil starvation.
You were having fun with that new manifold
!!!There's nothing wrong with that. You should be able to drive the balls off this motor without problems. The stuff I recommend over and over is about making the motor capable of surviving being driven fun like this.
