Failure to do so can result in three options.

1)You somehow happen to have gotten a PCM that has the same variance in your crank sensors already programmed in it. (Rare)

2)You get a PCM that has a negative variance (less timing less performance)

3)You get a PCM that has a positive variance (more timing, possible engine damage)

Would it be somewhat safe to replace PCM and then drive 3 - 4 miles to the shop for the CASE learn procedure?

As long as you don't go over half throttle (into Power Enrichment mode) you will be fine.

is there anyway to verify you have had a case learn done other than hooking up to a scantool?

Rogue, is 8-ball your daily driver? I am curious about the city/hwy gas mileage it gets, and what I will be looking at myself as I mod, mod some more, and more and more...

Yes it is, I get about 20mpg although before my gear change (3.69 now) I was getting about 26.
