Firstly welcome to the addiction.
Now as for your filter media it sounds as though you have some good stock.
Just make sure that you have a coarse and then fine filter wool before the other media.
This will help to filter out all the larger particles in the water before filtering through the rest.
As for plants....
Look on the FNZAS plants page. most of the commonly found, low light level plants will do fine.
Fighters don't generally go for plants but do like to hide in them.
Ambulia, water wisteria, java ferns, small crypts, star grass, most species of hygrophila, dwarf sag..... and more.
Most LPS will have mostly easy to maintain plants... but then again that can also be a great way to get snails and unwanted algae.
I think at the end of the day the best advise is to learn as you go. Thats how most of us do it.
