The plants you are "allowed" to have will depend entirely on the cichlids you go with. Many cichlids will uproot and damage plants and some others will just destroy or eat them, so you need to have a good idea of the stock you want to go with. That being said, there are many cichlids that do wonderfully with plants. As for lights, I would start looking at T5ho light hoods. Check out the vendor section here for starters or Drsfostersmith, aqua cave, premium aquatics, etc.
