Yes, of course you have to. Some daemons listen only on the specified
IP's/interfaces while others listen on "0.0.0.0" ( all ). If you scan
only eth0 and there is a daemon that only listens on eth1's IP you are
missing services that could lead to a security breach.

No, read above.

OS wont make a diference here, just application configuration.
