Hi When installing new floor [bamboo] and cabinets in the kitchen, are the base cabinets install over the new floor or over the old floor and new floor install around them? Thank you

i am wanting to put subway tiles on my back splash. just a basic brick type pattern. how should i center the tiles between a window and the corners ? as in. full tile on the window side and let them fall where they may on the corner side = half/quarter/third/whatever, tile to the corner. or center them in the space, and have partial tiles on each end ? also. the electrical boxs. i know i should get extensions. but i found that unscrewing the switches/outlets them come out far enough that i can fit the tiles behind them. i prefer this, as putting in the extensions will and a bunch of work. and going up to the bottom of the cabinets. i know the correct way would be to pull the cabinets. cut reliefs, tile and hang the cabinets. but this would be a lots more work. or. cutting the tiles to fit up to the cabinets. again, a lot more work. but i am thinking. that because the area is not really seen i could go up close to, but not flush with the cabinets, about half a tile. and leave a little of the wall exposed. ? the above range microwave. i can go up to it. but should i stay down from it a little ? thanx guys.
