What counts as more "simple" than something else is usually defined by the paradigm your working within (and so isn't really objective). For instance, Cartesian physics could be considered more simple than Newtonian physics, because it posits less kinds of forces (only contact forces, no forces that act at a distance).

On the other points I agree. All of Kuhn's main arguments (like Feyerabend's) would be sound if they weren't overstated.
