I had the same scenerio recently. We hung a 1-3/8 door (interior standard) on an exterior jamb set. We included the weather strip, threshold, door shoe to seal out the elements. As basements can be different from the weather outside, they can be another energy leak for your house.
So to be honest with you, I think it's a good idea to install all the accessories that make up an exterior package. Try to use a rabbeted jamb.
