Premature optimizations are something that you should avoid, you'll often be chasing completely irrelevant bottlenecks. I would strongly recommend just implementing things in the way that you find easiest to manage and using known standard fast paths and creating a well balanced scene graph, just be sensible, then do some basic performance testing it all looks good then move on. If you were getting 50hrz already then you have a problem, but at 700fps it suggests that things are doing just fine and nothing to worry about. As you implemented your shaders and introduce more data keep doing benchmark tests. I would suggest building up a family of animation paths that make the camera follow paths that are representative of application usage, then use these paths in your benchmarking so you got a consistent base on which to compare. As you progress you'll be able to monitor how your app is doing and spot when things start to go wrong, and if/when they do then you start looking into fixing the problems that arise.
