I've read an astronomer's comment some where that there isn't enough mass free flaoting around in the solar system to add enough energy to Venus to get its spin to anything like 'Normal'.
Not sure how much energy you'd have to put in just to get its currently 'reverse' rotation sped up, though.
Heck... throw enough 'Cassaba howitzer' rounds into the same spot to both, maybe, adding rotatonal energy into the ball as well as use the atmic energy side effect of breaking down the acid clouds into more usable forms. I think it ends up releasing more hydrogen into the sustem. Give back what's been boiled off over the last few million years.
Plus you dump commets etc for even more H20.
In all we'd have to invest a HUGE amount more energy into the project to get a Earth 2.0 but, as you say, our investments get a planet that later generations won't need genetic engineering to stay 'Human' that you've got to really do with people on Mars, Moon or other low density worlds.
Not at work.
You can place large sunshades in around a 30k km orbit around Venus. These would shadow any given area for appropriate lengths once every 24 hours during the Venusian day and create artificial night. Similarly large reflectors in the same orbit can illuminate any given area once every 12 hours during Venusian night and create artificial day.
Large reflectors and sunshades can be very light, made of aluminized synthetic membrane small fraction of millimeters thick. Such a sunshade 1000 km on a side would still only weigh a few thousand tons. Preserving the appearance of an earth like circadian rhythm would not be totally insurmountable even with present day technology let along with an technology equal to fully terraforming the earth.
The fact that Venus rotates backwards is no problem. Nothing I can think of depends on any planet rotating prograde.
