Some of the plants that you have listed would do perfectly fine in a medium to low light tank (about 1-2 watts per gallon), while others tend to need more light (3+ watts per gallon). There are some people that have reported success with growing these higher light plants with medium light, but most haven't.
I think the first thing to do is to decide whether you are tied to that specific plant list or would be willing to look at alternative plants that would require less light and maintenance. For instance you could go with Dwarf Sag instead of the Micro Sword, since it has a similar appearance but is less light demanding.
Should you decide to go with CO2
injection (which is pretty much a necessity in high light tanks) you'll need to rethink your filter. At a minimum you would need to remove the BioWheel as they are excellant at gassing off the excess CO2
that you're working so hard to inject. On the other hand if you don't inject CO2
then it can be used as is since it will help to maintain ambient CO2
levels. The airstone falls under the same category. It should be avoided if injecting CO2
, but is beneficial if not injecting CO2
Lighting estimates are based on the amount of light per gallon (not per plant). Each plant has varying lighting needs. These are generally listed as the minimum that a particular plant tends to need, and most will do well with more. There is a link in the Read This First Sticky that covers lighting and should be helpful as you work on deciding what you want to do.
The powerheads for extra flow, may or may not be necessary. You'll need to play with it to see what you actually need.
Substrate choice is good, just make sure that the EcoComplete makes up at least 50% of your substrate so that you're not wasting your money on it.
Something else that you'll need to read up on is Fertilization. There are also links for both CO2
and Fertilization in the Read This First Sticky.
