Also can I use any floor or wall tile or do they make tiles specificly for countertops?
Wall tiles are too 'soft' for a countertop, - - they do make tiles for countertops, - - they're 'hard' like floor tiles. Using wall tiles on your countertop is too much of a risk, - - first time you drop a glass or something you'll be in for a major repair. Check your local tile store for beautiful choices of countertop tiles.
It's all a matter of taste, - - personally I like the 6" tiles for countertops, - - boils down to how many 'lines' you want to see.
I like to match the grout color to the tile, - - it eliminates that 'checkerboard' look, - - but light grout colors can and will be a headache to keep up with. Keep in mind that grout always seems to come out lighter-colored than the sample, - - I always pick a few shades 'darker' to achieve what I want, - - do a 'test-ball' first.
