John, I'd suggest M2s all around(4 rather than 5, using a "phantom" center)plus the Parts Express sub. For a receiver the Denon 484 ecost refurb for $180. For a player ecost also has Panasonic F87 and Onkyo changers(don't saddle him with a single-disc player)in the $100 area. The player's included cables are fine and speaker wire shouldn't be more than about $10. I haven't considered stands for the mains.

Enjoy the music, not the equipment.
