If you use the configuration above, olsrd2 will not check the loopback
because its not in the config. If you want to use the loopback for
IPs, you have to add a second UCI "interface section" (for the
loopback ^^).

No, defaults should be sane.

If you have only a single mesh interface there is no problem at all. I
just prefer the loopback solution with two or more mesh interfaces.
