Pardon a bit off subject question, but how many hours to they plan before a major overhaul on these power plants? Does the same engine stay with a particular airframe for it's entire life - baring any outside damages?

I don't know what the overhaul interval is for the CF6-80* series, but it's probably somewhere on GE AP's web site. As for whether the engine stays with the airframe, that's up to the operator - however, in the interests of quick turnaround, the answer is usually no. The engine is swapped out for a serviced one and the plane is sent back out while the engine is serviced/rebuilt and inspected.
