2) This depends on the design of the heatsink, and how the air is applied. Generally, the performance gain will be very high, but it is hard to say how much
3) I hate to disappoint you, but it's not gonna work. As you can find out in the "Peltier cooling" section, Peltier elements consume much more power than they can transport. Now imagine you build a low-power system to fit into the rack that will get along with just 200W (a high performance PC consumes much more). To transport that, you'd need peltier elements with a total power usage of maybe 500 watts. Add the 200W transported heat to that and you need to get rid of 700 Watts of heat on the outside of your rack. How are you gonna get rid of that heat without using noisy fans on the outside? What kind of power supply are you going to use to get 500W on 16V to power the Peltiers? And besides, even if you manage to overcome the technological challenges, it's still an economic and ecological nightmare.
I have experimented myself with racks for sound insulation. Your best bet is to allow air in on one side and exhaust it on another, through air ducts with sound-insulating material. Here is a picture of the box I built (just from the outside; on the inside there's sound damping material, and ducts). It is extraordinarily quiet; I used to sleep in the same room and it was no problem.
All the best,
