This is probably a dumb question, but if I run a wire around the
perimeter of my house along the eaves so that it is as high as I can
put it, is that dangerous with regard to lightning?

Repeat after me:
We always disconnect external antennas from radios when we are not listening
to them, and especially when thunder storms are in the forecast.

Static can build-up in the wire from different sources. It's also a good
argument for having a transformer (at least 1:1) in your feed line that
provides a direct path to ground, in addition to your lightning arrester.

It can also be influenced by your tolerance for risk. If you don't like
rolling dice, then lightning protection, a transformer with a direct path to
ground and diligently disconnecting the feed line are all advisable.

Where does one find such a transformer? Why does it need to be at
least 1:1? What does that mean?

Where have you been?

Others available elsewhere, do a Google on 1:1 balun.

The 1:1 is for matching a narrowband dipole to a coaxial cable. The
whole point of it is to keep both poles of the dipole ungrounded.. I
don't see how it is relevant.
