Leveling a tank?

I have a picture to show all of you. The kind that an owner gets excited over. Water in the tank!! Here's my tank filled as high as I can currently fill it (the plumbing and overflow box aren't totally finished yet):
At the water's highest point I went ahead and measured the distance from the rim to the water line at all 4 corners. The right hand side of the tank is 1/4" lower than the left hand side of the tank (the water is noticeably deeper there to the discerning eye). So my question is, do I need to address that much of a tilt by shimming up my tank and if so, how level should it be? To within a 1/32"? A 1/16"? An 1/8"? For proper scaling, it's a 75 gallon tank with a 4 ft span, so that's 1/4" out of level in 4 foot (it's totally level front to back as far as I can tell).
Also, three more questions. One, should I have filled the 40 gallon sump with water and placed in under the tank before leveling the tank? Two, when I put my overflow box in, how tall should the teeth be in order to prevent people from seeing the water line when the tank is full? Finally, I plan to install an overflow where you can see the two pipes on the right hand side of the tank. My current plan is to make it with 1/4" glass and black silicone, then cover that with two pieces of black, 1/8" acrylic. Do you guys see anything wrong with that plan?
