Before I expend any time or effort- does someone have a general PCA
routine already written? If not, can anyone suggest a computationally
oriented explanation of not just the eig(covariance()) transform
but the various rotations that can be applied?

Here is an article about doing PCA in IDL:
http://www.dfanning.com/code_tips/pca.html
It might help.
Cheers,
