I custom built my own cabinets so precise levelling was not a problem and I don't have a tile floor neither. Standard counter height is 32 inches. A dishwasher is commonly fastened to the floor and the bottom of a countertop, but yours is gonna be granite, so fastening to the countertop wouldn't be possible. You'll need to locate where the dishwasher will be mark the holes, drill through using a masonary bit, shove it back in place and use lag bolts through to the wood subfloor. your base cabinets usually fasten by the rear straps to the 2X4 studding through the finish wall surface and also to each other through the stiles.
