You didn't say what cam you have in your engine. If it is a fairly high lift you may have some problems with the stock stall torque converter. This is because the idle RPM required for the cam may be very close or over the stock stall speed. The converter will then be trying to 'move' the car and you will have to keep a very firm pressure on your brakes or put the car in neutral whenever you come to a stop.
If you think you really need a 3200-3500 RPM stall speed; I'd suggest you wait to drive the car until you have installed a higher stall converter.
A separate trans cooler is always a good idea; even with a stock converter. For a street car I'd keep the stall speed just below the operating RPM of the engine when cruising at freeway speed. i.e. If you are running around 3000 RPM at 65 MPH then don't use more than a 2800 RPM stall. Keep in mind that the heavier the vehicle the stall speed of the converter will be in the upper range of the advertised stall RPM.
