Re: ugh, oil everywhere
As long as that top O-ring is in place and good here is no way it's going to throw ANY oil out of the filter housing unless the cap is loose, very loose.
The only other place that could expel engine oil would be the filler cap, it would have to be missing.
You sound as if you are comprehensively inept at doing anything automotive and just shrug it off with a "DOH".
Do your self a favor and find a shop to work on your car, especially the brakes.
