First, may I welcome you to Tropical Fish Keeping forum.
Before we consider plants, we should verify the light. Can you post a link to the online info, it may click with someone. This is important, as there is no point in buying high light plants like the micro sword if the LED is not up to that.
As for fish, this is only an 8g so the only suitable fish are going to be "dwarf" type species. Or a Betta of course. Before we consider fish, what are your tap water parameters? Many of the dwarf fish are wild caught and have specific needs when it comes to water. The hardness (GH), carbonate hardness (KH or Alkalinity) and pH are what we need to know; you can ascertain this from the municipal water supply people, they probably have a web site.
While we're waiting for the above, I'll mention our profiles, second heading from the left in the blue bar across the top of the page. Data on each species includes water parameters, tank size, minimum number for shoaling fish, etc. Most of what we suggest will be in the profiles.
