If that is the best setting for antialias then you need to render at a size larger than the taget resolution, load it into photoshop and size it down. Photoshop will antialias it in the process.
As for the moire pattern in your last rendering, whoa... if that were animated - forget it. It would be worst than watching a weatherman wearing a pin strip shirt on the local television broadcast. Once again, advanced rendering requires an advanced rendering engine. There are settings in Cinema4D that work to eliminate that.
Have you seen the latest news at the Maxon Site? It is affordable and if it works for Sony Imageworks, then I am quite sure that "I" will be happy also.
