basic Opengl, Lighting and transformations

I have created a basic opengl app that reads in elevations data from a binary file and generates the terrain. This portion of the code works ok. I need to implement rotations about each axis, scaling along z axis and normalization of vectors for lighting and possibly zooming. I have code for the normals inplace but it is not working. I would like modifications to my code only as well as good commenting within the added code. I can provide more details if needed and will provide the working file and data file, which has been created in MS Visual C++.
