1. Do you tend to doubletrack everything

Sweet jesus, no!

2. If not, then how do you tend to spread single mono tracks around
the stereo field and localize them well enough to tolerate them in
cans/phones.

Record them in stereo with 2 microphones. I do a lot of tracking with a
coincident or near-coincident pair, sometimes pointed off-axis of the
source so that you don't get that "everything is stereo so nothing is
stereo effect". Kicks the **** out of any potentiometer-generated
panning.
