I think that CD Manipulation is a category all of its own that is really more suited to stage-oriented magic... not to say that doing CD manip close-up is a bad idea.
If one were, however, to categorize this type of manipulation based on the stipulations that you've put into place, then I would have to say that CD manipulation bears the most amount of similarities to jumbo coin manipulation or coin manipulation in general (CDs come in a range of sizes, you know). In other words, if you were looking for techniques that can be adapted to CDs, then I would suggest that you seek out material on Jumbo coin manipulation.
As far as an overall category, I would give them their own simply because of all of the subtleties that are possible with CDs that are not with jumbo coins.
That is, of course, only my opinoin.
Best,
