Just a quick update... about a week ago, I tore down the tank, almost completely. I moved the fish into a 20G tank I have set-up nearby, so that all this activity wouldn't affect them, although I'm sure they didn't like being moved.
Anyway, the water from the tank was COMPLETELY removed. The rocks were completely removed. And many of the plants (not all) were completely removed.
While the tank was empty, I took the opportunity to squirt H2O2 directly on the algae on the back glass, and all sides of the tank glass. Completely saturated it, and left it to sit for at least 15 minutes, but I believe a bit longer.
The rocks were placed into a sink which was filled with water and a mega dose (not sure how much I used) of H2O2 was placed into the sink as well, and allowed to soak for a bit... then all rocks were scrubbed with a plastic bottle brush to remove as much algae as was humanly possible. Then the rocks were replaced into the tank.
The tank was refilled and I turned on the circulation pump (~600gph) for about 30 minutes. During this time the removed plants were given a quick H2O2 dunk (1:10 dilution in water) and then placed into a 1:1 liquid carbon solution... The plants were then gently rubbed to remove the algae, as best could be done.
The tank was then emptied once again, and the plants replaced, in addition to the new plants I had just purchased. The tank was then refilled, brought to temperature and the fish readded.
After one week, this is a video of what the plants and tank look like now:

I've since removed the bacopa species, and given them an algae removal treatment as well as the purple cabomba you see that isn't looking particularly well currently. I am hoping that it will bounce back. The green cabomba still looks absolutely fantastic.
