If you're actually there in front of your screen you should see if a GM is there, if the GM talks you will see it above his/her head. As for the chat, I don't see how it's any different from when you're leveling, items flood the chat pretty fast when you're killing lots of monsters.
You find it too boring? Why not kill monsters too, you can set your homun to attack one and go attack a nearby monster as well, right?
I wonder if you get more exp if both the player and the homun attack the monster.
