Start with reading and digesting "The Art of Electronics", by Horowitz and Hill. By the end of that you should be in a position to start.

You need to design for a certain power output into a known load, decide on a topology, A,B or D (C are for RF only), decide on supply rails, and input sensitivity. You may not NEED a preamp, but you can do useful signal conditioning, noise filters etc there.
