How do I start Clean

[Toriad]

ITs been awhile since I used the DB's and I want to start with fresh everything minus items, I want to keep the items from PEQ but i want to start with no npc's no quests, no loots, nothing. I forget what tables handle that.

I know how to start with no quests, but does anyone know if I can just drop the contents of like 4-7 tables to clear out the rest of it so I can start scratch, and if you could tell me how to clear out items to that would be great as i MIGHT decide to go that route as well.
