"Any Beige G3 can be readily upgraded to a 400-500MHz G3 via a ZIF processor transplant from a Blue and White"
I do not believe this is correct. The Blue and White has a 100mhz bus speed, the beige is only 66mhz. There will be issues if you try to swap newer CPU's into the older machines. Also, there were no 500mhz B&W's. 450mhz was as high as they went.

That's what the jumpers on the motherboard are for. You can adjust the multiplier and front side bus settings. Some people like me were even blessed with motherboards that are stable at 83MHz. This setting leaves the 33MHz PCI bus speed intact. My Rage Orion (32MB) is pretty happy on this speed.
