Filter: I'm thinking either 2 Aqua Clear 50's or a Fluvel 305
I'd say go with the Fluval 305 with the bottom tray full of pure Poly-Fill for extra mechanical filtration, you can get at Walmart or a crafts store. The other two trays can both have BioMax for biological filtration. Once the tank is cycled and establishedThe Poly-fill would need to be changed every 2 weeks, but other than that, you could go a month between filter maintenance.
substrate: 1.5-2" flourite (bottom layer) and 1.5-1" aquarium gravel
This sounds fine ... as an alternative, you could do Pool Filter Sand as a bottom substrate for roots to hold onto and then do gravel.
The heater and lighting sound good to me .. maybe another member with more experience can give an opinion.
