There are many examples on houzz of contrasting counters for perimeter and island. For example butcher block on island and stone on perimeter or a solid color on one and something with movement on another. I would only mix two stones if one had movement and one was fairly solid. The stainless on perimeter and something else on island sounds good to me. Here is a pic of stainless counters with what looks like a stone breakfast bar. (I hope I understood your question right). http://houzz.com/photos/3137660

Absolutely no problem changing up the carpet. Things to watch for......make the transition in a doorway, an opening or along a visual break in the rooms (like the corners of the walls). I would stay in the same colour range, but just go to the other end of the spectrum rather than change the colour completely.....like light grey going to dark grey, not light grey going to navy blue. You want the separation but an easy transition on the eyes.

I love our island bench in the mornings - I have 4 kids, 3 of which are teenagers, and the morning rush to get out to school is chaotic. The kids all come through to the kitchen at different times for their breakfast, which I have set up on the bench, and they can just grab what they want, sit on a barstool and gobble it quick. Then it's just the kitchen bench that needs a good clean after breakfast. don't have to worry with the dining table. Evening meals are a different story though, I believe families should sit down together at the dining room table.

Thanks , thats very nice. I like that style a lot. I found that Lighting Direct have these long industrial style ones which suited perfectly for going over a mirror cabinet and you can add an industrial style LED bulb. So Euro that have a Trade Me store sell nice pendants and decided to go with these for the 2nd bathroom.
