To Clarify, if I might.
The use of autothrottle is a recommended procedure, and..it makes life a little nicer. A manually flown approach is no big deal in this airplane...because...it is an airplane. Having the autothrottles control speed is just a bonus. This aircraft is extremely speed sensitive and accelerates quite rapidly. An autothrottle off approach is not a special procedure and in some cases it is a convenience to disarm them...as in a missed approach with a light aircraft and a small altitiude gain...to be able to manually control the thrust in this kind of situation is a nice touch.
I'm not sure what screens that you are talking of, however; there is a modification available to this aircraft that allows for installation of another display immediately to the Captain's left side panel and the F/O's side panel (near the left knee and right knee respectively) on which Jepp Charts, company operational procedures or anything that normally requires paper, to be displayed (paperless cockpit). No more Jepp Manuals.
I hope it helps.
