If I interpret your question correctly - here are my answers:
1) root hints - There is nothing you need to do, as BIMD will get
the information when it starts, based on the hints
that are built into the code. And the hints information
rarely changes.
2) Clear cache - There is no need to clear the cache, as BIND will
remove automatically any entry whose TTL has
expired.
3) Generating stets - I have no answer for this. You can generate
stats at any interval you want. The interval
might depend upon how busy the DNS server is.
