A simple fix would be to modify your GlobalLoad.txt located in the Everquest\Resources folder. Doing so will enable most NPC models to be displayed no matter what zone you are in. When you initially load everquest it will load slower but it should fix the npc model problem.
The following thread talks more about this change:

As an alternative I think it is possible to mod the zone file itself by adding the correct line to it so it loads the titanium version of the werewolves.
