You won't lose total par by having the LEDs closer together or further apart. The light will be more or less concentrated though over that given spot in the tank. The T5's crank out a lot of light, so I wouldn't be concerned about the par. What I think you want is relatively even coverage, which the configurations above will give you... the three strips of LED's grouped together in my opinion won't look right and isn't going to give you even spread over the entirety of your tank. You've got lots of light, so I wouldn't worry about figuring out what your par is... the advantage with the T5's and LEDs IMO over MH's is more even spread without hot spots and less shaded spots... I like the idea of maximizing the spread over the entirety of the tank with the T5s/LEDs. That gives you the most options to place corals and expect that they will get the light they need.
