The settings look somewhat normal. The settings will be slightly different from room to room. The sub distance should be set about twice the actual distance to account for the DSP lag time. The -12 is most likely due to the sub gain being a little too hot for Audyssey's liking, you can bump that -12 up to what ever sounds good or just leave it. I would start to play with the speaker size settings and see if you like the fronts set to small, I am willing to bet they are set at a crossover of 40hz, I would bump that up to 60 and see if it makes any difference for the better or worse.
Or you can just leave it all 'as is', since it sounds good to you, that is the important part.
