On size slowing development; This seems historicaly correct. With every increase in the size of a country costs of adminstration and corruption increase. If the colonial nations don't divert the wealth of colonies into the research pool then they will stagnate a la Spain.
Many of the innovations in military technology came from small-(ish) nations such as Holland and Sweden. They advanced because they did not have the resources of the colonial powers and necesity is the mother of invention.
The small independents are not just there as food for the world powers, most remained independent well past the time frame of the game, and their armies were always sought after as allies. I remember the shock of thinking that Helvetia would make a nice new aquisition to my country, until I saw the musketeer icon, and my troops getting slaughtered.
Personally, I think that the colonial cities, especially India and Indo-China are a little too valuable. Three or four cities there can bring in more income than your entire home nation.
