although,if all you want to do is play games on your amiga an fpu will be of little to no use.

as far as the oscilator is conscerned it is required for the fpu to work as the oscilator is a timer for the fpu (think of the oscilator as a sort of pace maker to help the fpu keep track of how fast to run) and sets it to its correct frequency(speed) in mhz.
Thanks Roy - So the 40MHz Xtal/ Quartz Crystal Osc/Oscillator and 68882 40Mhz FPU (PLCC) can and do work togther then? (Sorry I must have miss understood Retro, when he said the FPU would be harder to get)

It's good to know that the crystal is a necessary requirement of having a FPU and that a floating processor unit is beneficial for math intensive programs.

I guess this means that for gamers and WB3.1 users like me, it's not so important. But at least we now know - thank u
