The 3.8 L engines had troubles with overheating. I had a 93 Buick LeSaber with the same engine and I had to replace two water pumps. I would be wary of the shop saying that the engin needs to be rebuilt again, especially if it was only rebuilt a few months ago. If the same thing happened then they probably messed up when rebuilding the engine orignially.
I would suggest you do some reading on line. There is alot of good info out there. When I replaced the water pump the first time I used a remanufactured one and it died. So the second time I used a new one and it worked great.
There is also a phenolic fitting behind the water pump near the intake manifold that wears out and breaks. This will cause the engine to overheat quickly and it sprays coolant all over the place. They made replacement fittings that were made of metal. The fitting has a hose on it, I believe it goes to or comes from the heater core.
