Live plants are nice because they suck up ammonia - I like Anacharis because it can float in the tank, no need to plant it. Also Amazon sword is nice too. I had good luck with it in low light but it needs to be planted in substrate.
Giant moss balls are cool too. The need to be squeezed out once a week? in old tank water to get rid of debris and they needs to be rotated so the part on the gravel wont die off
Be sure the plants you get are actually aquatic. Most that come in a tube are not, and Bamboo isn't a true aquatic plant either.
There is a cool plant thread stickied on one of these forums - the one about homes and accessories, i think.
