Grounding A Radio ?

If I do, can I then rely solely on the coax shield being the receivers ground ? This would be from the radio chassis to the ground bar, of course. Then there's the question of the AC power plug's center pin grounding the chassis. There goes my single point system, I guess. Should I perhaps inhibit this pin with one of those cheater-plugs ? I'm also wondering about any safety implications if I do disconnect the chassis to water pipe ground wire I previously installed, AND also use a cheater-plug so the chassis isn't directly connected to the AC ground at the plug. Not sure if just relying on the coax shield back to the ground bar is safe ? Thoughts ? Also, my house 220 V input does not seem to have any ground rod outside, like I believe the new code requires. It does seem to have an interior wire running to my house's water line. I seem to remember from years back when the service box was opened that this wire was from the neutral bus, but not 100% sure. I would not really want to change or disrupt this present house grounding scheme by bringing this wire 125 feet or so to the new ground rod I will be installing. Any thoughts or suggestions on what would be the best grounding configuration for the radio (from a noise, safety, and possibility of any induced lightning surges) ?
