Introduce myself & some pictures!

Hey Scott, glad to see you lowered your height from your original 30", I see you may have reduced it twice? picture shows 24" but you also stated 22".

For your overflow I have a suggestion. Don't go with an end to end design. Stick with something smaller like 12-18". You can notch the glass and go with an external overflow. From my experience the larger end to end overflows do not skim the surface as well. If you use a smaller one you'll be creating a higher velocity flow from the tank into the overflow which will increase surface tension and actually skim the surface water better. With the end to end you're not going to get a good velocity nor surface tension and as a result will not skim the surface as well. Think of it like a vacuum cleaner, with a huge nozzle it's difficult to suck stuff up, but with a small nozzle it's much more effective.
