Most lens will have mark for the rear nodal point. Its the rear nodal that you want to be your rotation point. James have you ever used a nodal ninja for this type of work? It can be helpful as its designed to do this exactly thing. I don't use one so I don't know if they really work well but I know friends that use them.
What it can't do is work like a bellows with rise/fall/tilt/shift which will allow for changing the plane of focus which is very important at such high magnifications.
You can probably build a blows pretty cheap and easy if you are willing to give up auto settings.

I hate Nikon's autofocus system. This is the only area where I have real envy for Canon shooters.

If that is the method, then you need to get an offset so that the center post of the tripod is exactly at the optical center of the lens as it is focused.
This assumes manual focus with autofocus turned off.
