The switch on the passenger side door and passenger side window motor is connected in series through the 'passenger side' switch on the driver side door. If the wires have become disconnected or are intermittently disconnected at the switch in the driver side door both windows are dead. Check the wiring harness where it enters the door for signs of damage there which could also explain your mirror problem.
The passenger and driver windows are on two separate circuits through two separate fuses #47 and #50. Those two fuses are powered up by the power window relay which is controlled by the integrated control unit. Turn your ignition switch to the run position and check for power at fuse #47 and #50. If you have power at those two fuses then you have a wiring problem / connector / switch problem. If you don't have power at both fuses then the power window relay may have failed. You need the service manual for your exact year to locate the relay because Honda moved stuff around during the production run. If the relay is OK, then there may be a problem with the integrated control unit and you need the service manual to diagnose its operation using input / output tests.
None of the preceding has anything to do with the power mirrors. Unless the power mirror problem is a red herring and does not occur at the same time as the window problem, about the only thing that can cause simultaneous problems on the mirrors and the windows are connections at the driver door switch or some kind of failure in the harness where it enters the door.
Taking the door apart to access the door interior is not technically difficult. It is a bit time consuming the first time because you need to be careful if you don't want to damage things. There used to be a guide in the Prime Wiki with pictures; but, the Wiki appears to be unavailable right now. The service manual has all the details you need to get the lining off without damage. If you are impatient, best to farm it out to somebody who has the service manual or who has done it before. If the mechanic is not an NSX specialist or doesn't have the service manual, chances are yo may get the door back with some double sided tape and glue holding things in place.
