The easy solution is probably to use a system like IPplan
<http://sourceforge.net/projects/iptrack/> to handle all your addresses.
It can mark subnets for DHCP, and export an XML file, which can be
converted to a configuration file for DHCPd with XSLT.
I'm running something like 700 subnets and three /18 networks in that
way, and so far I have found it to be extremely useful.

Correct, just write the other options outside the subnet definition,
then they will be the default settings for the subnets.
