You probably know this already but the preferred tactic for dealing with prop walk is to use short bursts of reverse to get water flowing over the rudder, at which point you should have sufficient steerage. You need to really goose the throttle to get enough speed on to both overcome the initial prop walk and to counteract any cross-wind or current that will push the bow over (usually not in the direction you want to the bow to go).
Short bursts in the first sentence, then really goose it in the second.
The second one is correct.
99% of folks who mention prop walk, a constantly recurring theme, is that they simply don't get the throttle up enough to start moving backwards.
Sure, you'll get a little prop walk at first, but then the movement overcomes it.
I always suggest practicing this in open water and next to an open side tie dock.
Practice, practice, practice.
