If you're going to the trouble to re-tile, I would strongly suggest that you re-tile the whole tub surround. Just doing one "patch" area with the cementboard and tile is do-able, but the amount of work is a lot more than you may be expecting, and the end result won't match.
The board that is there is most likely not because of any damage from a leak, but from repairs done to the shower and probably the installation of a new valve.
If you're using cementboard, there is no need for drywall under it. You may have to fiddle a bit to get the surface layer to be the right depth.
BTW, you will likely end up with a lot more than one home improvement book. :) I highly recommend the Time-Life series.
