I would make up a cheap DIY co2 system. Search the DIY section and you'll see what I'm talking about. For ferts go with Greg watsons ferts, they will cost you around $25 shipped for your tank and will last you nearly 3 years. Your plants are probably growing well due to a large presence of nitrate, due to the stocking. Your bacopa doesn't look to be growing that well. In my 135 I clip my bacopa once every week (approx. in half), and by the next week it will have already hit the top again. I once thought that my plants were doing well, but I have learned that they aren't doing as well as I had thought. Check out some of Takashi Amano's work. He is the father of planted aquariums as they are seen today.
With only 1W/gallon, you are limiting yourself to what plants you can have. WIth higher lighting the options open up. Your tank is looking good, don't get me wrong, but it has the potential to go crazy. You have a healthy environment for the plants. Now take it to the next step, and you will see a considerable change. If you get really good you will end up selling your clippings, either to local keepers, or to LFS.
