We got the aircraft down safely with no damage to people or property; [and] afterward; we all talked about what we could have done better. -The Captain didn't say a brace signal for instance. For the flight crew; time to communicate is at a premium and with the workloads and distractions; some things were missed such as typing out a letter to dispatch via ACARS.-The cabin crew has a very long list to read in small print on a folded cardboard paper; [which] in my opinion; should be made shorter and simpler. One stated that it was hard to read the print when the adrenaline was pumping. -I would like to see flight and cabin crew emergency training accomplished together someday here; to focus on building crew coordination when an actual emergency arises.
