At least there's now also ndppd (not yet in Debian, working on that), in case
one doesn't receive the first one routed.

Routing nets smaller than /64 will deprive yourself of autoconfiguration (not
of router advertisements, though). It's possible and might make sense depending
on the use case. But using a /48 makes more sense if you can do that.
