For the XP3, possibly with the exception of the bio-media (ceramic rings), everything you need comes with the filter. Sometimes the ceramic rings are included as a promotion (haven't seen that lately, though); if not, you'll have to buy them. The 30ppi and 20ppi pads that come with it will last a long time. If you want to used bio-chem zorb or carbon, though, it's good to buy extra, as they'll need replacing after a month or so. Using the microfiltration pads is up to you (you get one with the filter)--some people say they cause the filter to clog more quickly and don't use them. I make my own from generic floss that I but at a petstore, and haven't had any problems with them.
Someone else will have to help you with the Fluval media.
