Oil Cooler
From what Im told the benefits introduced by using that cooler are easily outweighed by the benefits of running a better oil.
If you need to cool the oil, make sure you have the pump to support it and circulate your oil through a front mount heat exchanger. That provision on the block unbolts easily enough to remove it and replace it with a simple oil filter.
Your stock radiator is the same with or without the oil cooler, so yes. Check out Lt1info.com for a schematic of the plumbing.

The oil never leaves the motor with the factory cooler provision. That 'block' just circulates coolant through a coil inside it to remove and in some cases add heat to the oil. In most climates, the factory oil cooler is said to add more heat to the oil than it removes.
To circulate the oil out of the motor to an aftermarket oil cooler (B&M supercooler) you'd need a bypass sandwich adapter (keeps oil filter in stock location, thermostatically bypasses some oil for cooling as temps allow) and some nice lines to safely plumb the oil to the cooler. By nice I mean braided stainless and an fittings to ensure a positive leak free seal. Dont want a line coming off or leaking when the life of your motor may depend on it.
