That will help, yes. I do that as well as pulling the fuel pump fuse before replacing the fuel filter.
I would imagine that there would still be considerable pressure unless you pull the fuel pump fuse. One stall won't hurt anything. This procedure is listed in the FSM after all, so it can't be that detrimental. Obviously, relieving fuel pressure via CONSULT-II would be the best way to go, but not everybody has one of those lying around.
If you really are wary of pulling the fuse, I'm sure the job is doable without, just be extra careful to avoid getting gasoline in your mouth or eyes since there will be more pressure.
