The 82 / 68 pF are the main compensation for the amplifer loop. They act together with the FET transconductance.
The 220/100 Ohms are likely to counteract one pole in the amplifier, to give it a little phase boost so that one could push the frequency limit a little further. My fist though was this could be related to the OPs GBW, but this would be at lower frequency. Usually there is some unwanted pole somewhere above the GBW of the OP and my guess is that this is the one to counteract. This tweak likely depends on the details of the OPs and maybe other parts used - so even if one would get another OPwith 4 MHz GBW, one may still need to rethink the resistors and find the best value experimentally.
It may be a good idea to run a simulation (e.g. LT spiece) of the amplifer. The Chopper part should be reasonable separate (lower frequencies only), so it should be OK to leave that out. The result of the simulation depends on the models and would thus not be enough to get a final value. However the simulation would help to get an idea how critical the values is and get an idea how the resistor would effect the response, e.g. ringing with a square wave input.
