Simple inverting or non-inverting op-amps aren't properly differential, you'll either want a 3 op-amp instrumentation amplifier (see the diagram in >>2493415) or a single op-amp differential amplifier (pic related). Just find whatever op-amps are specced the best for your application, and ensure the input impedance isn't too much of a problem. In this case I think PSRR should be your main concern, but you should go through the calculations to figure out what the major source of noise will be anyhow.
