Low-Tech 36g bowfront tank questions..

I was hoping for some help/advice with upgrading my tank lights so that I can have a good low-moderate tech setup without the need for CO2. I want a light that will support the most variety of plants possible.

I also had a question about fertilizing. Is the information on the post it section mainly for high tech co2 injected tanks? What is recommended for low tech tanks as regards to fertilizing?

I was looking at this light: http://www.amazon.com/gp/product/B001F9AJDS/ref=ord_cart_shr?ie=UTF8&m=A16EQQFLPSKFJZ.

I think this one would fit right on my tank since it is 30 inches long and about 4 inches wide.

Would it be worth making a glass lid and getting a different light that sits up higher to lighten the entire tank more? I am really new and would love advice from anyone. This is my first tank ever!

Thanks for looking!

I got my idea of what I want my tank to look like from this post (kinda long read):

I plan on getting the same plants she has in her tank. I also have an amazon sword and micro swords already in my tank with an 18 watt t8 light. She mentions using TPN+, what would be similar to this with dry ferts?

I am still looking for a good light fixture if the one above is not enough.

Would a 55w compact from ahsupply be too much light for my tank?

I just thought of another question, I have so many! Since I just have regular sand as my substrate right now, should I add some eco complete where I plant/re-plant? I do have some osmocote fertilizer which I have been using like root tabs. Would that be enough or should I get a layer of eco complete where I plant?
