AFAIK you can drain the oil from that car by pulling the drain plug, although I wouldn't suggest using the ramps. Keep the car on a flat surface to ensure it all drains out.
You asked about the oil filter cap removal tool. I would definitely recommend getting it. I bought mine from the dealer for $28 (Canadian) but I can see them all over eBay for much less. The cap is made of plastic, and I've heard it can be prone to breaking. You don't want to be changing the oil on a Sunday morning, have the cap break, and not be able to drive the car until you can get a replacement from the dealer.
