Ya, more coil questions

I'm going to be switching from a stepside to a fleetside bed here in the next day or so hopefully, so I went ahead and bought some Jeep rear coils so I could switch those out while I've got the bed off. My question is, what is the easiest way to get the rear coils off? I've heard horror stories of coils going flying off in all sorts of directions wrecking things left and right... so I want to make sure I'm not going to run into that on my little project.
