That white fluid is emulsified oil and water. Coolant is getting mixed with the oil and the engine whips it into a sort of milkshake.
The head gasket probably failed along on or more of the cylinders. This would explain both the oil/water and the rough running. Have you noticed a loss of power?
I'd run a compression test to confirm it. But it sounds like you need to replace the head gasket.
Sorry about the bad news,

The security system (Passlock) is having problems, it's typical on those trucks. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue.
