Well, I think Monte's wrong on both of the stat blocks and "heroes" counts, on the first point in general and on the second point for the adventure in question.
The main problem with stat blocks is that in 3E, they're too blasted long! I can see where they get to save a lot of space by just referring to the MM, but if they hadn't designed things so that the block had to be so long, then they wouldn't have to worry about so much space. So what do I do? I write up the blocks and print them out to use and mark up. It's a hassle, quite frankly. I do have a Filemaker Pro database of the monsters, laboriously cut and pasted from the SRD and entered by hand, that can generate my blocks more easily. But again, putting that together was a hassle.
I want more detailed stat blocks including, at least, their AC (including touch and FF), Initiative modifier, Movement rates, Attacks, Reach, Saves, and a listing of their SA and SQ, Feats, and relevant skills (Spot, Listen for most).
With respect to "The Mad God's Key" and use of the term heroes. It's a Living Greyhawk-approved/oriented module. Ergo, the PCs are assumed to actually BE heroes. That's one of the foundations of the LG campaign. Use of the term heroes whenever the PCs are described is totally appropriate. If they aren't heroes on at least some level, they don't belong in LG.
