I will post this evening.... As for the concrete, make a future plan for the lift and when you pour block out 12"X12" on the floor and double the depth in that area atleast (8" in those areas.) This would be for a 2 post however something else may be of interest to you. It may seem like overkill, but make it one and done I say.
Also, one of the pictures I post will give you an idea of what happens when you don't upgrade on the structure......
