Sounds like you're on the right track with everything! I would do some research on your canister filter and try to learn about the media. It will need to be cleaned and serviced about once a month or so, so it would be a good idea to familiarize yourself with it. If you post the make and model I bet someone here has used it before and can give you a guide for maintaining it.
