Swords will grow in any substrate, I have used fine gravel for 20 years, and more recently am using sand in some tanks. Echinodorus species are my main planting, and they grow well. But they do need nutrients, they are heavy feeders as kangy mentioned. If you have other plants that are not in the substrate, such as your Anubias, the best general fertilizer is a comprehensive liquid. This feeds all plants in the tank, whether floating, attached to rock or wood, or rooted in the substrate. My poersonal recommended brands are Seachem's Flourish Comprehensive Supplement and Brightwell Aquatics' FlorinMulti. The substrate tabs such as Flourish Tabs for the sword will also be good, not necessary but it will help.
On your light, that sounds fine, although knowing the tank size would help determine if it is sufficient.
