Wherever you buy your fish, ask them if they take returns and in what length of time, or if they give store credit for fish you want to get rid of. If so, you can stock up on some angels and just see how it goes. If they don't get too aggressive and everyone in the tank is fine then there's no need to get rid of any of them (although I'm not sure about the lone discus; I'm sure someone else can chime in on that). One or two plecos with some driftwood would be good [verify the full-grown size of the pleco and their diet (carnivorous, omnivorous, primarily algae, wood-eater)]. A school of cories are another bottom-dweller choice, but again, I'm not sure how they would fare in an aggressive tank so I'll leave that to someone else. In a 75g tank, you've actually got a good amount of options for an aggressive tank. You can add parrot fish or other south american cichlids; it just might be more difficult keeping plants the way you want them.
For plants, check out some vendors and see if they have low-light packages. Anubias, java fern, java moss, and jungle val are certainly popular choices and do just fine with little light. If there are others that you're interested in, we can guide you through which ones would be better suited for your tank. If you plan on using the standard fixture that comes with the tank, your options will be very limited, but a nicely planted tank still may not be impossible.
