Yes, but do not put all your trust on OSPF alone, as its designed for full
on / off failures. Redundancy often becomes a manual process in Wireless,
and is really solved by good a monitoring system / policy. The reason is
that most wireless links start to fail partially (packet loss), instead of
full outs. As a result OSPF will not always detect properly when it becomes
necessary to switch routes.
One of the good features that Trango offers, is including ARQ now in all its
radios. It lets us more easilly record packetloss from ARQ statistics.

In looking at that and some other things, I realize I really should
plan for redundant links to the POPs from the NOC. I want to plan
to have it so that if the primary link goes down, another like will
take over. Probably looking at OSPF routing. That brings up the
questions. Do I need to eventually have a link from every POP to
all other POPs it can see, or do I just plan for one backup for
each POP, or somewhere in between? Is there a better way than OSPF
for doing this?
OSPF is certainly the best bet for this scenario. With OSPF, you
will have the self-healing you are looking for. You don't HAVE to
have a redundant path to every pop, but doing so would obviously
give you a more resiliant network. I sent you an email offlist as
well.
