I'm in California too. My dealership charges $29 for an oil change, lube, & filter. They will also drive to my house to pick up me or my wife and drive us back to the dealership to pick up the car. Going to the dealership for oil changes is also convenient for any incidental repairs that I may have them do. It isn't the least expensive way to do repairs, but it is often the fastest repair, since my wife and I both have busy schedules and two kids. And the repairs generally have the advantage of being done by a team of professionals who regularly repair the same type of repairs I need from them.
for anything unusual, i get my information from HERE and print instructions for my dealer to follow, if i'm not doing the repairs myself.
As for how to clean oil drips off your engine cover, you can use soap and water, or a degreaser like some diluted Simple Green.
