There are 2 10mm bolts to remove and a bunch of plastic fasteners that just pop out with a flat bladed screwdriver, and push back in by hand.

You should get some ramps to make it easier to get under the car. When you get your oil filter be sure to get a new drain bolt crush washer. There is nothing special to installing the oil filter other than lubricate the O ring on the filter with a little oil, and put in on by hand as tight as you can. Don't use the wrench to install it.

There are pretty good instructions in the owners manual.
