I've run similar set-up on BBC engines, and all was well. I actually like the Q-Jet for nitrous apps, because of its superior fuel metering capabilities (assuming it is working correctly!).
The plate system would be fine, and I generally stay at the 125 level. You should retard your timing when using it, better safe than sorry. MSD sells several different devices that will retard timing using your 6AL, from simple to multi-stage nitrous specific controllers.
