Get a coreless motor; I use a Tacon 3970KV motor, and it's nice and quiet, but even being "just" a 2-pole motor it still does backflips no problem. (for the record, I'm using a Trackstar 120-amp short course ESC -- it runs smoother than the stock ESC and costs half as much.)

I have an Integy wheelie bar that bolts to the underside of the rear skidplate, and has a single rubber wheel. (most wheelie bars for anything smaller than 1/10-scale use plastic wheels, which do nothing to help keep the vehicle moving in a straight line.) The wheelie bar is designed for "riding wheelies", as you describe it, but the mounting plate is just a piece of sheet-steel, so you could bend it down until the wheelie-wheel is nearly touching the ground. Keep in mind this will reduce your off-road clearance, though, but if you don't drive off-road then maybe you don't care.
