So you need a spoke-wrench, yes? First you need to find the size of the spoke-nipples on the wheel in question. I am going to guess they are DT Double-Butted 14-15-14 gauge. Or Sapim spokes. So if you measure them and they are 3.23mm - they have a European pedigree. My favorite spoke-wrench for working on these is here:

Shop around to see which spoke-wrench you
think will be most comfortable and maneuverable to you. They are all (except DT) pretty cheap, so there is financial room to not hit the nail on the head your first time out of the gate.
I will assume you have already read through this, but for anyone who hasn't:
