AutoCAD 2009

[#1]

I'm at a point where my hard drive is in need of a reformat for reasons unrelated to AutoCAD. When I go to reinstall AutoCAD, how can I be sure it will reinstall with my correct information so it doesn't think all of the activations have been used already?

If you have a valid license i don't think there is a limit of how many time you can activate.

Right, the automated system will likely lock you out of multiple activations as you expect.  But since you have a valid reason for reactivation, you can contact Autodesk Activations directly and they can provide you with an activation code if your online activation fails. 

Please call Autodesk Product Registration and Authorization:
