The primaries should be placed so that zone updates are convenient to
perform; the secondaries (you'll probably want more than one) should be
placed near the users.

The zone data for your subdomains can be included in the zone file for
your second level domain, but this doesn't allow for decentralized
administration. If your people in CA, OR etc. need to maintain their own
subdomains, you should delegate to them instead.
