I have a program I use a lot, it's called "MySQL Query Browser", You can get it from
http://www.mysql.com/downloads/ , and its free - small stuff like putting in or changing to new zone coords are easy and quick with this as it gives you a "visual" on what you are doing. It also has a great "tutorial" on the bottom right hand corner.
or if you don't want to get into it, this should fix it;
Code:
REPLACE INTO zone VALUES ("nadox","","Crypt of Nadox",-643.06,-1349.17,-40.87,45,0,227,0,0,1,"",-2030,1500,2000,500,2000,0,0,0,0,255,0.75,0.4,2,0,0,0,500,2000,0,0,0,500,2000,0,0,0,500,2000,0,0,0,500,2000,"",1);
Also on the grids for this zone; if you see they are not right, I think I had fixed a few of the old ones, aside from the new ones I made (mobs were walking through the walls and all), you might have to use REPLACE instead of INSERT
I still haven't figured out how to place the POK book in the Gulf of Gunthak - I just put in two translocator GMs (one in gunthak and one in POK, where the stone is supposed to be) - if you want the quests, I'll post them too.
