Since nobody answered yet, I'll do. I usually put the same things, in an Eheim or any other brand.
For the bio part I use Eheim Substrat Pro. I used to put Fluval ceramic rings, but my "mentor" told me that Eheim was better. And it is actually better (I believe), since I used Eheim Substrat Pro, my water is much clearer.
For the mechanical part, I use Eheim Efhimech, but also Fluval prefilter rings. I feel that the mechanical part is bit less important, and Fluval prefilter rings (which is more cheaper) do an acceptable job.
I usually use only the "big black sponge" for the mechanical part, and not the "white wool". I feel that the white wool gets dirty very quick and needs to be changed often, since you can not only wash it.
I would also invest in an UV Sterilizer, great stuff to keep the aquarium clean and without algae.
