No, there is no reason you can't mix DLZ and 'file' zones.  In fact file based zones are required for zones that support rfc 2136 dynamic updates as DLZ doesn't support that.

It should log as normal.

That depends on your secondaries.  The serial number for a zone is really to support replication via AXFR & IXFR (full and partial zone transfer).  If you aren't using those mechanisms then there really isn't a requirement that you increment the serial.  It's probably a good idea to do so though just to stay compliant with other's expectations.

I don't believe it does.  All DLZ does is move the storage mechanism from a file to a DB.  You can think of each row in the DB as being a line in a tradditional zone file.  So whatever the required file syntax is DLZ is the same.

Yes, that should work.  See above.
