Sounds fine to me. Are you rinsing your pads in tap water? I wouldn't put them back in the filter wet with tapwater personally, since I'd want to keep chlorine as far away from my biomedia (your bioballs and ceramic noodle thingies) as possible. Many people advise that you rinse your media in tankwater. It might not be a bad idea to rince out one of your bio baskets in tank water each time you clean the filter rather than just shaking both up. I can understand the desire to not touch one of them though 
.
FWIW bioballs are typically used in wet/dry systems, and may not be as efficient as other bio media in a canister. I'd be tempted to replace them with something like Eheim's efhisubstrat, or pick your submerged bio media of choice. I might also swap the ceramic noodles and your other biomedia (i.e. noodles first) but i'm just wierd.
Anyhow, don't see anything wrong with what you've got or are doing other than i'd avoid getting tapwater in my canister like the plague.
