I have a 48x60' hangar that I want to insulate for the upcoming MN
winter. What are my options, and what works the best?

Options tend to be fiberglass batts and foam panels. Fiberglass is cheaper and
doesn't burn as well. It can be held in place with spring wire placed between
joists or by stapling chicken wire to structures to hold it in (among other
techniques). One disadvantage is that rodents like to make nests in it. Many
types of foam are flammable, some highly so, but the panels can be glued in place
with construction adhesive.

I will also be adding some much needed overhead lighting. Any
recommendations here?

The most cost-effective lighting is fluorescent. Standard ballasts don't work
well below about 60 degrees, however, so you need commercial fixtures. Home
Depot in this area sells Simkar commercial units with ballasts that work down
to below freezing, but even that isn't going to be good enough for deep winter
where you are. Halogens work in about any temperature, but they put out lots
of heat. That's great in winter, but lousy the rest of the year. Possibly the
best choice would be some of those "yard security" lights that look and work
like streetlights.
