Just an FYI for the brace, you could cut those braces out and replace them with a piece of glass 12-18" wide that you silicone to both sides. That is how my 220 is braced (same dimensions as your 180 except 30" high instead of 24"). They ARE important!
Why are you going to plug the overflows instead of using them? Since you already have them it will be very easy to run a sump.
