Paint your house and ceiling first. You are probably asking for trouble if you put the floors down only to paint over the top of them. If you can, remove the tiles in the kitchen and paint just behind the line of the splashback too. Once painting is done replace kitchen benchtop then splashback. I would call the bathroom its own job and do it individually, unless you only need to paint the ceiling and if a tiler doesn't need to be brought in for anything else in the house? A lot of bathrooms now are getting tiled from floor to the ceiling if this is the case, paint the ceiling first, then tile. If walls need to be painted, it wouldn't really matter if you did them first or last, though if you did it first expect to do some touch-ups. I guess if you really wanted, you could do the first coat before tiles then second after... I don't exactly like stopping and starting painting, so I would do the walls (if they needed to be done) in one hit, after its been tiled. Well that's the order in which I would do everything... Really, for what you're asking, the painting could be done at anytime, but to make life easy on yourself, I would definitely recommend doing it before the floor.

I think the brands you have listed are good! What colour were you thinking? How have you gotten the opportunity to import carpet? I hope it's not too expensive for you!

Anyone know where to get these matte black pendant lights from?

Provided there is 1200mm clear between the breakfast bar and the opposite bench then by rights, you should have ample room and if that's the case, I think I would opt for the design with the kitchen on the eastern side. My reason; you get a much greater feeling of open plan by having the dining and lounge on the North/South plane. I like the large WIP in this one - on paper at least. The second plan somehow feels wrong. I personally don't like the idea of having the breakfast bar being located in the lounge. If it were me though, I would ask for a 3D CAD plan of both kitchens [to walk through on the computer] before making up my mind on which one to opt for as it gives you a much clearer vision of what the finished kitchen will be like rather than looking at a flat plan.
