There is no reason you can't use the acrylic tank and get great results. It is true that if you were doing this from scratch, I'd tell you to get glass, but there is no real need to replace the tank.
As for the aquascape, your only limited by the size of the open holes. How you handel it is do wnat the SW reef people do. Use several smaller objects in place of one large one.
To solve the light issues, consider using a screen over the holes. This will prevent some of the light reflection. You could also replace the light fixture with two smallers ones, each just big enough to span the holes.
What ever you do, do not attempt to remove that top plastic frame. It is critical to the integrity of the tank, and cutting it off will cause the sides and front and back to bend and fail.
