Two lights are better, but if you use thee pendants, then position the two stools should be in the middle of the center and end lights.Although they will look very huge. Pictures would help.

Rather than removing the edging, I would add to its width and this wil make the cabinetry look custom and paint it white. I would also keep the corner shelving and replace your accessories - one item/shelf and related to each other. You could add a great fixture instead of the pot light, change the faucet and hardware. Suggest carrarra marble backsplash (don't put the rack back up behind stove) and there are so many pattern choices. It's also interesting how they have laid the tile in the last picture, which I think would work really well with your set up and will save a bit of money on marble. A dark quartz or granite would be complimentary and warm up all of the white.

Without knowing any more info , I'd say its near impossible for anyone but you to know what colour/s to choose -- do you want the house to blend in but have its own style , or do you want it to stand out ? What colours are your main furniture items and even kitchen etc ? For xxample , if keeping the beige walls , how about doing the eves and gutters and garage door in a tangy ( bright , but not glaring ) orange -- this would work with the existing colours and not require a complete repaint . BUT if your kitchen was mainly various shades of , say , green and teal , and your lounge suite and duvet covers were mainly blue hues , that may 'feel' funny , clashing with the exterior ? Of course , blue and beige exterior may not work with the brown aluminium , as youve recognised . Another option ( a bit hard to tell from the pictures ) is that a light grey ( repaint the beige ) with mid-charcoal base boards may work with the brown aluminium , then a bright colour on the gutters and front and rear doors to suit -- anything from sea blue to bright yellow , orange , red , even white or off-white would probably work .
