When I got my XP3, everything came with it, including the biomedia. It would have been good to check with big al's to see if that's true of the one you purchased. Most likely you would have had to purchase the biomedia, though,---they seemed to have stopped that particular promotional offer (but could have reinstated it, I don't know). I've found big al's prices to be very competitive with other on-line retailers and regular petstores (the one exception was an aquatic store near me that was clearing out its supply of ceramic rings and was selling them at half the price of big al's). To cut down on shipping costs, I usually order big and stock up.
For biomedia, you can use just the rings, the stars or a combo of both (I do). I've had my XP3 for almost 2 and a half years, and I've never had to replace the biomedia. When you clean the filter, rinse the biomedia in the tank water (don't let it dry out, I keep a small bucket to let it sit in until I'm ready to put it back in the canister) to preserve the beneficial bacteria. One package of the rings is good for 55 gallons, the stars more.
I've never had to replace the sponges either. As with the biomedia, rinse them in the tank water (not tap water) and keep them in some tank water until you're ready to reassemble the filter.
You don't absolutely need the carbon--if you use it, it should be replaced monthly. If you don't use it, you can buy extra biomedia and put it where you would have had the carbon.
You don't need the microfiltration pads either. You'll get one with the filter, but I think they're a bit pricey for what they do. I used to cut generic ones from a roll of floss I bought a Petsmart, but I've found that the outflow will diminish more quickly when they're used, and a few times they clogged the filter, so I stopped using them. Your choice.
I think you'll also get a package of something called Chem-Zorb with your filter. I've never used it--it's been sitting for over 2 years in a box.
Your choice as to what to use, but the most important media is the mechanical media (sponges) and the biomedia (rings and/or stars).
I live in CT, too. Big Al's ships within 48 hours and it's usually taken 5-6 days from the time I've ordered to get the shipment (unless they're out of something and what I've ordered has been placed on backorder). They ship from Niagra Falls/Ontario, I believe.
