I think that's a very sound plan, everything on the list is light. I wouldn't change a thing personally on your zero, as you're familiar with the setup you have, simply demonstrate you can hit where they want you to. JHC-II is dead right however that you are expected to arrive without abnormal ideas, and the PH will likely want as many variables removed as possible such as high sight ins. All sorts of interesting misses occur in Africa and KISS is the name of the game, most clients arriving fresh in Africa shoot less than our on average well hunted membership here.
On that note sounds silly amongst a group that shoots as much as this, but practice your butt off with the rifle from 30-300 yards and you'll be a very happy hunter with a very happy PH. My brother can shoot, and shoot well, but for whatever reasons once on the ground he had a hell of a time hitting an apple at 100 yards. Nonetheless his shooting on game was good, as evidenced by the red mark. If you can quickly off hand a 500ml waterbottle from 50-150 with your -06, you'll see nothing but a tight, content smirk on the PH's face and will hit the field without further ado.
