As someone who has done research on circadian rhythms for more than 30 years, I can assure you that your analysis about resetting your clock is absolutely correct. The single most important factor in resetting as quickly as possible is exposure to light - especially natural sunlight - based on destination time. The other valuable tool is to take melatonin at the destination's bed time.
As one who has rarely, if ever, flown F class on an international flight (best I've ever done is C class), I probably should not comment about keeping the shade up other than to say that is what I would want to do myself, based on the above information. Maybe someone should invent the opposite of eye shades - light goggles one could wear to simulate natural sunshine.
