Lose the bio media.
In fact i would recommend selling the fluval altogether on ebay or soemthing and buying a simple two little
fishies phosban reactor for $30 bucks to run your carbon every now and then when you want. Take the money you made and buy a nice frag of cool zoas.
The coralline will grow on its own time...just maintain your alk and calcium levels either by supplementation or regular water changes.
Zoas, mushrooms, and leathers would all do fine in your tank. As would LPS such as frogspawn, although the frogspawn would be happier with more lighting IMO.
You will want to get some powerheads or other means of better flow in the tank.
How you achieve that is really up to your budget and/or willingness to do a little DIY work if you wanted to do a cls.
As far as test kits. I recommend getting salifert calcium and dkh. Any cheap test will work fine for nitrates as that number will reduce signifigantly or go away on its won as your tank matures and your husbandry habits improve. Ammonia and nitrate arent necessary IMO. If you are missing a large fish....find it and get it out.
I also recommend getting a pinpoint ph monitor instead fo test kits. Over time it probably costs a little more, but it is nice to know at all times what your ph is. Once you get a feel for your tank you wont even need to test alkalinity as you can simply see when you need to add buffer according to what your ph monitor tells you.
