pwrflpills - don't worry, plants really aren't that complicated. It's all about providing light and nutrients. CO2 injection isn't necessary in low light tanks, but it will still help.
I have a low maintenace tank with mostly crypts, anubias, and java fern. It takes almost no extra work to keep it going. I add some fertilizer sticks in the gravel every few months, once or twice a month add some liquid fertilizers, that's about it.
edit: you also don't need any special filters. If you're injecting CO2 it's a good idea to keep surface disturbance to a minimum. Canister filters are good for this.
