I've had two of the three Bonnies that I've owned do the same thing as you described in regards to coolant disappearing and both ended up blowing head gaskets within 2500 miles of it starting.
Both vehicles were around 120k miles.
As for the other issue...... not sure, but maybe it'* related and due to the engine overheating?
Ram, You sure about head gaskets blowing? If so, you are one of the very few that have had head gaskets blow on a 3800 at that low of miles.
Dontgiveuphope, I suspect a LIM (lower intake manifold) gasket failure. Check the oil, if there is coolant in it, drain it out ASAP or the engine'* bottom end will be destroyed.
