What manner of arcane magic must I invoke to determine how many bits are in each pixel of a BMP image, and also divine its color code format (whether it is a gray-scale image or an RGB image)?

Bitmap pixels can vary in size from 1 to 32 bits. Bitmap files can be grayscale or color and use several kinds of encoding for color information. Check out this Wikipedia article for more details:
