Shrouding never hurts, but the documented benefits tend to measure in the low, single-digit percentage realm. More important is to seal the fans against the rad, be it with a full shroud or just regular foam tape. Extra fans... if you want. As rads go, Thermochills rads have below-average air resistance, so it's a little less important. If you have room and don't mind the extra noise, feel free.

It boils down to basic physics. In the process of passing through the first rad, the air will become warmer. Thus, the second rad will be trying to cool the water down using this same (warmer) air. The warmer the air, the smaller the temperature difference between it and the water in the second rad. The smaller the temp difference, the less heat will be removed from the loop. The slower the air moves, the more drastic this effect will be, but it'll never go actually go away, even with high-powered fans.

3/8" tubing is still plenty for chipset cooling and can seriously help reduce clutter around the socket area. If possible, making the NB block the first after the radiator will ensure that it gets the coolest possible water, since it usually benefits the most from cooler temps (But it's not critical).
