So...let me get this straight.
You're trying to get this board, to play MP3 files, from the uSD card.
Is that right?

The datasheet:
http://cdn.sparkfun.com/datasheets/Widgets/WTV020SD.pdf
says that the files are to be named 0000.ad4 or 0000.wav - so did you use the .ad4 or .wav extension on the filenames? (of course 0001.ad4 (or .wav), 0002.ad4 ... on successive files).

Also, page 19 shows an MP3 player hookup diagram - play / pause button connects GND to P07.
Also, you can only use a tiny speaker directly on the unit (8 ohm, 0.5 watt)
