I think you'll find the 737 Emergency Descent checklist pretty much basically the same as other Boeing aircraft, blueloo.
Start switches - continuos
Thrust Levers - retard
Speed Brake - deploy (a change in aircraft config is not recommended if structural damage is suspected)
Descent - Initiate
Target Speed - Mmo/Vmo (a change in aircraft speed is not recommended if structural damage is suspected)
There is nothing in any of Boeing's checklists, as far as I'm aware, that require the A/P or A/T to be disconnected, if engaged.
Initiating the descent can be either by A/P, or manually.

Hi'er - only what I am saying is that other boeing aircraft dont need the checklist - you just do it. The 767 from memory has no emergency descent checklist - you dont need one! It assumes you know how to do a high speed descent. (The PNF does have a drill to follow which covers various things in the 737 checklist)
Its finally dawned on me as to why I was told about the commonality issue with the 737-200. Supposedly, it doesnt have an automatic PA for a depressurisation for the Cabin, therefore, the checklist requires the Captain to Announce , and later on the Seat belt signs to be put on, whereas the newer versions have the automatic PA, lights to full bright, and Seat Belt sign on.

Perhaps it stems from Boeing's philosophy that the 737 is usually the first air transport jet that most pilots will fly (it's incorrect of course, but I have been told that that was the Boeing "thinking"), and that the procedures learnt on it will form the foundation for future (Boeing) types.
That's just an "imo", though.
The Emerg Des is a recall (memory) item, which means the crew will launch into it, once it has been decided that is the way to go - which is pretty much what you are saying you do on the 767 - the difference being the checklist for the Emerg Des will have to be read from the book, once the recall items have been completed.

Nosebleeds? How the heck did they get nosebleeds? I've never heard of a nosebleed during rapid depress training in the chamber, nor in a rapid descent situation. Unless the excitement of the whole thing sent someone's blood pressure through the roof perhaps. How on earth do passengers always seem to end up with these mystery ailments after an incident? The entry into a rapid descent isn't really all that violent, but I'm sure a few of them will want compo for their backs being thrown out of whack too.
Anyway, it's probably a good idea to wait for the investigation to determine precisely what did happen before we go about critiquing the crew actions.

This time - 
I agree totally with Amos2!
Nowhere in my 737 QRH/ops manual does it say to conduct an emergency or rapid descent for crack/delamination. Of course there may have been more to it which we don't know, if so then up to PIC.
2nd thing to do in a non normal situation : "sit on your hands"

I dont agree Tankengine with you or Amos: In this case why not wait to see A) what happened and B) What they did - before you tell them whether what they did was/wasnt correct.
Amos, how do you know they didnt do it as per the manual?

Sorry Blueloo,
I have a manual in my office - do you? [maybe amos has one?]
If not a "normal" cracking/delamination [which is almost a regular occurance with 737s] then as I said, it is up to PIC to do what he feels best.
It will be interesting to read the report.

you're not that good these days! 
Some things AREN'T in the manual - Commander's discretion has always been the overriding, discretionary factor that was often the final decider.
YOU, amos, as much as anyone, would be aware of that.
(Pssssssst, were YOU really THAT good??
)
