In-amp Amp Filter

I'm using an instrumentation amplifier to read a pressure transducer
with a 0 - 5v output (grounded signal source). I want to use the inamp
in the nonreferenced single-ended (NRSE or pseudodifferential) mode to
eliminate any potential difference between the ground references of the
transduces and the box where the inamp resides. I also need to filter
the input.

Using the inamp in the NRSE mode as described above, should I use a
differentail input filter (resistor in each inamp input, cap across
inputs), or will a single RC filter on the + input, with a cap to ground
be OK?

Thanks
