Creature Cataloguer
OK, finally found some time to look at this here feller. 
the creature is not overly complex, and fairly straightforward. For the most part, we can just keep Shade's work. I don't know how long ago the conversion was done, but in my experience the older the conversion is, the more work will likely have to be done to get it right.
A few things I would draw attention to:
Creatures that had a movement rate of 9 I normally translate into 20 ft. they were slower than 12, which is now 30 ft, so I usually like to keep them at the slower movement rate. 9 x 2.5 = 22, which could be rounded up to 30, but I prefer 20.
Should it gain temporary hp from the energy drain? Not all creatures with energy drain attacks do, IIRC.
I would make note of the gem-eyes as that is interesting and flavorful.
I don't think that is being used?
Did that really say 22 rounds or was that a typo?
I'm assuming that's where the deflection bonus came from?
This is not reflected on the attack lines.
These attributes are not reflected in the writeup. In fact, it looks like the flavor text is mostly copied and pasted with little editing.
we'll fix that - muahahahhahahahahha!

Dungeon #14 said:Two gems of seeing are fitted into its eye sockets, giving the golem the ability to see hidden, invisible, out of phase, astral, and ethereal objects or creatures.

Dungeon #14 said:A protection from normal missiles spell and a limited wish are employed to give the creature immunity to all nonmagical weapons.
I don't think that is being used?
Dungeon #14 said:Any creature approaching within 15' of the golem must save vs. spells or be slowed for 22 rounds.

Dungeon #14 said:Attacks against it are made at -2 to hit in addition to other penalties.

Dungeon #14 said:Armed with a huge two-handed sword which does fearful damage in addition to the energy drain, the black golem is a powerful guard for any evil magician's lair.
This is not reflected on the attack lines.
Dungeon #14 said:It is whispered that a magic-user of 21st level or above with a minimum Intelligence score of 19 can use the libram of constructs to create a still more powerful form of the black golem, a semisentient construct which can create juju zombies and other undead, commanding them in the service of the mage who created it. This nightmare creation can charm person by gaze and has other powers which hardly bear contemplation.
