The 3 spawns really do not hit for much. You can kill them fast if you want, but it is probably better just to keep focused on the main named.
The adds can (and probably will) attack your merc healers. That can complicate heals in a group where mercs play that role. In this case, kill the adds as they spawn.
Named took a looooooong time to spawn. Seems to be much rarer than most nameds in the zone.
