No.

Superman Returns is a sequel to Superman I and Superman II, so it's a separate universe with elements of those two as backstory. But it's a separate thing. It ignores III and IV.

As for using info from Crisis, we don't know what to do with that yet in terms of the larger adaptation multiverse. But we're not going to merge pages because of one throwaway line.
