from my experience:
1) You will definitely need to use Lipo battery packs (3 cell). The 6 cell Nicads can’t seem to turn the brushless motor – at least not in my case (as specified in a previous post).
2) The motor selection is also appropriate. I earlier posted that I was going to install a 4500kv motor (not to be confused with RPMs) but instead opted for a 3300kv motor (lower RPM) and it works great. I also think the 90amp ESC is plenty big enough. However, I couldn’t tell from your post if your ESC is water cooled as well as the motor.
