It's possible that you may not need to ground the arm at all. It really depends on what cartridge you're going to use.
I'd recommend puting the whole system together without a tonearm ground and see if you have a hum problem. If there's no hum, then the best thing to do is nothing.
If you do hear hum noise, then obviously a ground would be required. In that case, I'd send the arm to Brooks Berdan for his expert attention.
