Aside from the noise and vibrations, it is quite possible the other engine indications were pretty normal. I don’t see much damage to the engine itself, apart from the missing fan blade.
The evaquation checklist on the 737 calls for (time permitting) FL40.
You would be able to see some of the damage to the leading edge from the cockpit in a -700 model.
As for the pilots actions, the aircraft and passengers/crew are safely on the ground. Not much to debate.
Job very well done!
