I would pin down the GH, your water supply people can tell you this, they may have a website. If you find it and can't fathom it, post the link and I try. GH is very important and one should always know the GH as it can impact fish and plants.
On the filters, you do not want any chemical filtration in a planted tank. This will be running in competition with the plants for nutrients (chemical media absorbs or adsorbs nutrients, plus it alters the water chemistry which often works against the plants). And depending upon the fish selected, less filtration is better with plants. I go into this in more detail in my series "A Basic Approach to the Natural Planted Aquarium" stickied at the head of the Aquarium Plants section.
