I was just wondering...The cargo canister is supposed to be expendible but
what about the three good shuttle engines that are in it's tail?
How are those recovered?

They're not. By current plans, they will be engines that have already flown their rated life (about 10 missions) on the shuttle, and hence are ready for the boneyard anyway. Earlier shuttle-based-heavylift schemes put the engines and electronics in a pod with a heat shield and parachutes. It could be done, but it would add complexity and development cost, and it is not as attractive today as it was when the engines were expected to last 50 missions. -- Welcome to Mars!
