I'm thinking of getting a 36g bow front too, so I'm going to follow this journal with some interest.
I would suggest, however, switching out that yeast co2 reactor and go pressurized. DIY co2 is more suitable for nano tanks <20g's. You'll probably run into algae issues with that t5. You an get an Aquatek regulator, diffuser, and paintball 20oz cylinder all got around $120 (check out my journal in my sig).
BTW, i love the c-series of Fluval filters. I have the C2 on my 10g dwarf puffer tank. That C3 should do you pretty well.
