Yes, it right. I'm using similar setting in my home network.

It may better that rtadvd(8) have global default setting of the
values.
Unfortunately, rtadvd(8) shipped with FreeBSD 4.9-RELEASE and
5-CURRENT are very similar to KAME's. :)
It seems that KAME folks separates static configuration from dynamic
configuration.
