Firstly Hello! and Welcome
How high is your tank, 30cm?
Those lights you have are great lights! You will be able to grow plants like Java fern, Anubias, Dwarf Sag, Cryptocoryne sp. (Crypts), Ambulia, Amazon Swords Java moss and christmass moss.
That heater should be fine. (someone want to add on this!?!)
Filter: The Sunsun in that link will be fine for you tank. if possible get a slightly bigger one. Eheim 2213s are over rated!
Fish: A nice big school of 20 or so tetras will look really awesome! Along with maybe a dwarf cichlid (a blue ram Pair?). There are also Dwarf gourami, Hatchet fish, dwarf chain loaches, Cory catfish, plecos, the list goes on. Go to Hollywood Fish Farm they will be able to point out to you all the right types of fish that will be suitable to you.
I suggest you start out with some simple fish and slowly add more fish to your aquarium after you have cycled it. Also ottos are great algea eaters, but to avoid algae in your tank it pays to have good water flow in your tank (try have all the leaves moving).
Substrate: There is a substrate called midnight black which is a fine grit and is really good to plant in. If you are not wanting to do multiple layers of substrate You can use JBL Root Balls.
Also look into a topic called Aquascaping!
