IMHO, 110w seems a bit excessive and may be a hassle. I am in the same situation, `scaping a 20 gal long tank right now. Last year I grew out a 20 gal high with 55w PC, DIY CO2, and a simple AC external filter. The medium light plants grew well and filled in nicely after a couple months.
I decided to move to a long tank for a shift in layout dimensions. I plan to keep the 55w PC on it. Now that the tank is more shallow I'm planning a layout for medium-to-high light plants. I'm `scaping with the intent to keep the 22" reflector biased to one side of the tank. I have upgraded the filter to a Eheim 2213 and will keep the DIY CO2 for now.
I'm actually in Indianapolis as well. Unfortunately, the aquarium stores here usually keep a poor selection of plants, so once I wrap up the planning I may end up placing an order for plants online.
