Yes, you should run the pump when you add chemicals to your water,
You add D.E. to a pool when you do a fresh filter clean. You also add D.E. if you have to backwash your pool more than normal. When you backwash the pool it is also dumping the D.E. out so it needs to be replaced to keep the grids covered so the pool can filter properly. Hope it helped

You add diatomaceous earth (de) powder to a pool based on the size of the filter. Most pool filters have a plate on the side telling you how much de powder you need to add. If your filter does not have such a plate, the general formula is that you add 1 lb. of de powder for every 10 sq. ft. of filter area. That is, you need to measure the length, width, of your filter, taking the pleats into account, and use the formula "sq. ft. = length x width" to determine the square footage of your filter.
it depends on how much chlorine is already in it .
As soon as I notice a different smell in the pool, it helps to add a focculant to the skimmer and after 24 -36 hours backwash the filter. Shocking the pool at this time should control the odor.
Yes you can add liquid chlorine to a pool even if it's not circulating
