1. This is the oscillator circuit.
2. The circuit should work over a wide range of crystals with no modification.
b. The crystal is designed and specified to work with a load capacitance. Since the two caps are in series, you would use 2X the specified load capacitance.
c. The resistors are not critical at all. The shunt resistor should be high value so as not to load the crystal. The series resistor limits the amplitude. If the series resistor is too low, the crystal might be damaged. If it is too high, the circuit will not oscillate.
3. The division is: 3579545/60 = 59659.083
multiplying that number by 50 gives: 2982954.1 hz.
Be advised that this is an obsolete part. If you have one, fine; but if you want to buy some, good luck.
