Try a light grey. I wouldn't go beige with the yellow. Dark wood looks great with grey walls. Yellows and brown also work well with grey. So pick a light grey and good luck.

There are several companies which can print pictures on tile. This is fine for interior work but the kiln fired method is superior for outdoor use. If you have any particular photos or art, you can transmit images through email, ftp upload, or send pictures to be scanned. This allows wide flexibility for resizing to the installation of your choice and allowing photo editing.

Option 4. I would not have more than 2 different cabinet finishes. Darker, grounded look for the base and island, with lighter, airier look for the uppers would balance the room.

I'd put in a tile backsplash. Stick with a solid color tile so your bottles won't get visually lost. Solid color doesn't have to be boring, look for interesting shapes or textures, and play around with different colors of grout to make a statement. The one in your picture looks very similar to the 2nd picture below.
