The stencil buffer tutorial is recommended background reading (but try to focus on principles, and not on details/code, and don't worry if you don't understand it completely. Browse, don't memorize, the 50 pages). It also covers fake shadows in section 4 and 5 and contains little info on soft shadows in section 6.4.
