if you go through the 3dSmax modelling tutorial on how to animate shooting a laser beam at an asteroid, it shows you the modifiers you can use for making a realistic asteroid shape, well rock shape and how to texture it.
thats particular oart of the tutorial teaches you many important principles of how to use modifiers and materials. You could just read through the materials section to get a better understanding of materaisl and the tools availabel for manipulating them?
that way you can have more fun controlling how your models will look instead of holding back and waiting for someone.

many of the other EnjoyCG video tutorials will teach you how to make and apply materials also.
