Cool before covering and before putting in the fridge. You can spread the PP out to cool more quickly; chilling the pan(s) you spread the pork out on first will speed it even more. When cool place the PP in whatever storage containers you're using but don't pack thickly at all. Loosely cover then fridge. When cold you can combine the contents of the containers to save space then cover tightly.
You can reheat at any convenient temp. There is no need to reheat slowly but you can if you want. (I reheat 300-350.) Stir once after 25 or 30 min, then again every 10 till evenly heated to serving temp (145-155), no higher. (Reheating to higher temps means the pork will cook again, not something you want.)
