You could make an estimate for your squads, since you've already lvl 157, your squads would be like 7+7+7+5+6 or 7+7+7+6. Using that  kinda of squads would probably be more efficient and fast.

On the others topics, Yes... GUMI should make another double exp events, so players could gain a quick exp during quest.

My advice is not to use any Demon Slayer Batch 7*, Cause they cost 42 costs in your squad, and that wasn't a very good decision. Either way, in you level right now I would probably guess that you might not gonna have any problem at all using your cost with efficient.
