rc.conf is a shell script on BSD systems. The OP will need to write
his own parser to read it. Take a look at the wiki's list of
parsers[0], specifically shlex[1]. I haven't used it to parse things
like rc.conf, but I imagine it could be useful.

Nothing in the standard library handles interface configuration,
though there may be a package somewhere to help you with that. In
general, yes, you'll be writing your own scripts wrapping around
system commands. As Evan says, be smart and keep those scripts
around. As you figure things out, generalize your scripts and create
some useful classes, etc.
