Yes, and the top and bottom also. Basically you want a duct from the grille to the radiator, so if any air comes in through the grille, it won't go around the rad.

Normally a slightly higher temperature is good for fuel efficiency. A few ecomodders have switched their 185°F thermostat for a 195°F model. You probably shouldn't go above 205°F too often.

That depends on how much you pay for fuel. Here a gallon costs about $6. The two motors (one of the radiator, one for the intercooler) cost maybe $12, plus switches would bring it to $20. Plastic, screws, wires and other random stuff was free.
In my case the grille block is a must: My turbodiesel is already quite efficient, so with efficient driving it is wasting very little energy in the form of heat. In sub-freezing temperatures I have trouble keeping at operating temperature (>80°C/176°F), even with grille blocks and engine insulation. So in my case it's about keeping the engine at a healthy temperature.
