I think the layout will look really good as you get more plants in and they fill out. That's a nice piece of wood, and I like how you laid it in there. You already have a great start.
As for ferts, they are pretty cheap when done dry, and will certainly help. A couple of years worth for my 12 gallon was only $30. I have no idea if they are required for you though. Probably not.
