What's your experience so to speak with tropical fish keeping. Are you familiar with the nitrogen cycle. While you decide on what you want to stock the tank with. It's best to get all equipment needed with maintaining a happy and comfortable environment for your fish to live in. Start cycling the tank fishless and add a little bit of fish flakes every two days whilst monitoring your ammonia, nitrite and nitrate levels.
For your tank stocking id do either a pair of angels, pair of gouramis (kissing, any dwarf gouramis, pearl) as a showpiece pair in the tank and then fill it in with some schooling fish. You could do a school of 5-6 Corys or loaches as bottom dwellers. and two more schools of 5-8 tetras (Not neons, angels are known for snacking on them), or if not tetras then some cherry barbs (playful, active and hardy) or harlequin rasboras.
This is my two cent anyway.
