EDIT:
Ok here is where I am at. I have added a spawner to the healer huts outside of skara. Made the spawner, made it moveable, put in chest and added two lines
whip/movable/false/STEALABLE/true
Loot,RandomClothing/movable/false/STEALABLE/true
I set the max count to 1 and the clothing spawn to 20, the whip count to 1 giving a 1 in 21? chance of spawning a whip.
Question 1, can I add a probability to spawn the whip without the clothing workaround. I.E. if it were on a mob I could say like /ADD,0.3/whip how can I do that here in this chest?
Question 2 since this is a world chest, can I force it to re-lock or trap itself, If it was one I spawned I know it would re-spawn locked.
(Figured #2 out, if you are looking for an answer too, look into adding a spawner outside the chest with the SET command and then using "props" to target the chest with SetItem, for example the spawner text could be:
SET/locked/true/locklevel/40/requiredskill/45/TrapType/DartTrap/requiredskill/20/traplevel2/TrapOnLockpick/true
Hope this helps someone)
Thanks for you help.
