I honestly like your floor very much and think that if you end up with creamy colored cabinets, it would be just fine -- the floor and the counter would play off each other. (Would have the backsplash out as quick as I could ready my hammer though! eep.)
I might paint the island a nice gray, chosen to match the counter and floor. (Otherwise, if you are dead set on a new floor, go gray there, as it will leave you just one color to work around.)
Anyway, lots of people seem to love Uba Tuba, which can appear as black or green, so I think if you just remove the other elements you don't like, you may find you don't mind that one so much. I'd take the backsplash to a cream that matches the cabinets, but maybe in glass for a little sparkle. Then add hardware you love, and whole new kitchen! :)
