Yes, and you really should use one. The two most important things with
signed zones are that your signatures don't expire, and that the right
DNSSEC RRs are included in the zone. So not only does it need to be
resigned after changes (to include the proper DNSSEC RRs), but also
periodically make sure signatures don't expire. Here are a few of the tools
written for that purpose:

Looks okay to me. Here's what your signed zone looks like visually:
Although, it looks like you perhaps didn't increment the zone serial, as
only one of your authoritative servers is running a signed version of the

No, this is only for resolvers that are validating answers, not
authoritative servers that are serving signed zones.
Of course, if you're using the server for both and you would like to enable
validation (i.e., of other signed zones), then you'll need to enable
