Tank is Cycled - Help with filter Maint.????

Hi all!

I first started my 75g aquarium on 10/16/06, and the cycle was fully completed by 11/01/06.
Thanks to everyone here, I had no fish loss or stress...!!

I now have a question regarding my filter maintenance.

I have not touched it yet because I didn't want to mess up the cycle.
It's a Fluval 405. I used what they gave me for filter media because I didn't want to waste the stuff, but I am going to just keep ceramic rings and glass wool in there.
OK, right now there are 4 compartments of carbon which I am going to toss.
There are 2 compartments of Bio-Max which I am also going to toss, but only one compartment at a time. The Bio-Max and carbon will be replaced with ceramic rings and glass wool eventually.

So, when should I do this? Is it too soon for filter cleaning since it just cycled?
Also, do you think ceramic rings and glass wool are enough to keep things "happy" as far as a good, healthy tank?

P.S. I already have some ceramic rings in there and those I will never touch.

Thanks for your advice!
BTW-The fiter instructions say to change the Bio-Max after 3 months...should I leave that in...
Knowing my setup, what would you do?
