It may not be necessary to increase the rotational velocity of Venus, if a suitable array of sunshades and reflectors can be established in Cytherean orbit. Since the object of increasing the planet's rotation is to avoid overheating the surface by exposing it to solar insolation for too long, simply regulating the amount of solar radiation reaching the surface, and where that radiation falls, at any particular time would achieve the desired result without having to resort to fusion engines, mass beams, or any other "active" technologies.
As far as cooling the surface is concerned, Carl Sagan's 1961 proposal using genetically modified algae could probably work (though at least several centuries would be required). An interesting article listing several proposals is here.
