get a seperate hard disc and transfer the files as you go along if you can burn these files to DVD even better so you have a back up plan if the Hard disc (aka scratch disc) goes tits up...
high speed fire wire 400 or 800 lots of RPM for the scratch disc 7200 or higher
PS it's all fragile and don't like get disturbed when your coping...
Have fun
NZ looks brilliant
PPS
copy files full fat so you get maximum resolution
PPPS it's easier with a mac (but not much)
PPPPS test it before you go
