Do you have access to another Mac? If so, you can maybe start your MacBookPro in FireWire Target mode. Essentially, even with a wiped out Operating System, you can press "T" while booting your Mac and it will appear as a FireWire disk to another connected computer - you can then at least copy your files off your MBP to the other computer.
See here for details.
ADDED: The slightly harder method, if you have access to another machine, is to remove the disk from your MBP and put it in a USB disk caddy and attach that to another machine. Good luck!
