Is that a brake assembly on the end of the stepper?

You'll want to check the other stepper motors, as X and Y are often fitted with smaller steppers than the Z.


Regarding the tool holder, if it's been in there for a while, there may be a bit corrosion helping to stick it. You might need to get somebody to push/pull the release lever, while somebody else gives the toolholder a hit downwards with a hammer and block of wood.
No idea about the end of the stepper,

Judging by the state of the table corrosion is highly likely. I'll try and get some penetrating fluid in there to do it's work before getting the hammer out.
