how often do you replace your filter cartridges?

Sounds ok. As long as you do your water changes. Every situation is different, but i've been doing this long enough that I just go by feel. 
I know that the 350 has 4 slots I just think that's overkill. You don't need the activated carbon unless youre trying to take out meds or tannis. I bought some blue bonded media sheets and cut my own to fit. I got a 12"X 10' roll for $7 on eBay. I cut off the filter media from the plastic frame and use the frame to back my media. Really inexpensive

I do two 40% water changes every week and use Seachem's Prime as a conditioner. I test the waters parameters once a week after the second water change and so far everything's been pristine.
Yes the 350's do have 4 cartridge slots but i think they are necessary only because my 55 houses a Sanchezi piranha and they tend to be messy eaters.
How about the bio wheels? Ive never changed those...still adequate?

Bio wheels house the bb on that filter. If they get really gunked up they stop turning. If that happens try a rinse in tank water.

Only change when it falls apart and rinsing no longer works. Bio wheel never needs changing
