New to SW - taking my time

Ok,
th tank is 75g & I'm setting up a 30 long below.

I was not planning on drilling the tank, I thought about it, but was put off by the big sticker that says DO NOT DRILL on the bottom as it is tempered glass. . . is this just a C.Y.A. by All-Glass?

I was planning on doing a pretty straightforward sump-in-stand setup.
I'm using a HOB Overflow -- 650 gph.

Yes, i would drill one hole in each corner...build a weir around the outlet, so the water drops into the weir then out through a bulhead down to the sump...

The flow all depends on things like height the water has to rise back to the tank, the pump, the diameter of pipe used..There is a lot to concider...
