Check in the WorldBuilding forum, there's a DB in there with moving mobs. I believe the title is something like 'Moving mobs Anyone?'. I'm working on one myself, but it needs a lot more work.
You can use EQAdmin for the top down map view and create paths from there, or write down /loc info from in-game and use a tool like MySQL-Front to edit the data, or even notepad and then source it in. The options are endless... ok, maybe not endless but there are lots of options. :lol:
Hope this helps you at least a bit.
