I think you can start by de cluttering. There's too much going on. If you want to keep the bedspread, I would pull some colors from that. :) Teals, browns, whites. It would make a pretty room.

Hi did you finally use nano white? Pl let me know asap as I have to decide for my kitchen. Thanks angela

If you love the marble tile, go for it! You can always buy a stainless or white range hood backsplash like this http://www.wayfair.com/Air-King-Range-Hood-Back-Splash-SP2430-AXK1174.html to slip in place when you are cooking something really messy. I have a travertine backsplash and use a stainless sheet when frying. It works great and no worries about stains ruining the stone.

Veneer with White PU is a great Option. Alternatively you can go with Duco which is slightly cheaper than PU. Laminates always have a sharp edge unless done with the right expertise. Fabrics, if going with white, should be scotch-guarded. Mostly, white PU will work on table tops too, but if you want to use a sturdy option, go for white lacquered glass or White marble.
