Safety is not a one size fits all and, for cars like the S2000, adding incomplete safety systems may result in a more dangerous car, rather than a safer one.

Do you know of a good source of entry-level info on the topic?
I just installed my first rollbar and intend to upgrade to seats and harnesses.
When choosing my seats, do I need to be thinking about HNR?
What sorts of options are out there, aside from manufacturer?

I strongly suggest you get a containment seat. HANS is for F-R collisions, a containment seat will keep your head in place in an offset/diagonal/sideways impact. There are other HNR systems that will help in these types of impacts.

These cars are tight inside, so it's not real easy to have a dual purpose car once you make the dive into safety, in comparison to something like an E46.

Schroth also has some great material, as does most of the harness manufacturers. HANS also has some good documentation.

Everything is tied together as a system. A few examples:

Your rollbar should place the harness bar within ~200mm
Your rollbar should place your harness bar no lower than 20* from your shoulders
Your shoulder height is positioned by your seat and your seat rails
Your shoulders need to align with the passthrough holes for your harness.
If you have a harness you need a rollbar, if you need a harness you need a seat, if you have a harness you need a head and neck restraint.
