The mic is easier than the preamp. Any of the Sennheiser MKH series mics are
notable (when you put one up) for how quiet they are. They're not hard to find at
rental houses, either, so you don't have to buy one.
A preamp for your job is going to be harder to find. You'll need more gain than
the usual 55-65 dB that you find in studio preamps. I'd suggest a TRP from
AEA Associates, but that's designed for ribbon mics and doesn't supply phantom
power, so you'd need an outboard phantom supply for the mic. Maybe the new
RPQ from AEA would be a good try. It's two channels, supplies phantom power,
has up to 80 dB gain, and a little high and low frequency filtering. AEA will
let you have one on a trial basis.

I'd suggest that you poke around a film sound forum or newsgroup to see
what people are using for Foley work these days. That's a field where they
make very clean recordings of often very quiet sounds. There was a company
that made a preamp and equalizer that was pretty popular in that business
ten or more years ago. I'm thinking Cinema Engineering, but that may not be
the right name. A quick Google search didn't turn up what I thought I was
looking for. I suspect that today, the Foley recordists are mostly all using
Sound Devices digital recorders with their built-in preamps, which are darn good.
Maybe one of those would be a good try. You should be able to get one at the
same rental house as you'd find a Sennheiser MKH40 or so.
