I feel like I should also raise the question of if you really want a car with that low of miles. Every mile you put on it, you may be the kind of person that watches that odometer tick up and hate yourself for slowly killing what attracted you, and others, to that particular car. I've seen this a lot with people that buy low mileage cars and end up buying something else to eat the majority of their daily miles.
However; for the general fear that people have of super low miles... Don't worry about it. I agree that the IMS bearing is probably a good idea, along with a complete fluid flush. Transmission, brake fluid, oil, differential, coolant, etc. All of them is a good idea. It gives you a good idea of where you are starting and all that has been done and most of all, gives you the peace of mind.
Good luck! Hope it all goes well, and I would LOVE to see some pictures
