Chuck,It sounds like you're on the right track.
I didn't follow any guide books but found mounting the bed,then running boards with splash apron attached and finally the rear fenders was the way to go.
Trying to wiggle the running board and splash apron with the tab in with the rear fenders on is a surefire way to scratch up either the cab corner and/or the fender.

Don't ask how I know!
