I have never seen a chart for such purposes - usually it is taken as read the clearance with new bearings and new crankshaft will be correct. The engine data in the repair manual or the data book will state the maximum journal taper and ovality and the maximum bearing clearance when assessing a worn engine.
The use of Plastigage makes finding the bearing clearances much easier and is very accurate - moreso than measuring the internal diameters.

Usually it is sufficient to assume the rods and mains are ok unless damage is suspected and simply measure the crank journals and compare the results with data.

Depends on how hot and how long it was running without coolant. Let the engine cool down. Then add water to the radiator, start the engine, check the water level and keep adding water until it is full. Make sure that the serpentine belt is ok. Check to see if there are and large coolant leaks. If the engine has a miss or is blowing out white smoke from the exhaust pipe then damage has been done. If everything seems ok, then let the engine cool down again and recheck the coolant level. Make sure that the serpentine belt is ok.
