Re: compression results
before you pulled the head off you should have done a cylinder leakdown test on cylinder 2 to see where your leakage is coming from... by looking at your compression #s you probably have bad piston rings, maybe a bent valve or a valve seal problem

Re: compression results
not really, easiest way to test if piston ring is bad is to put a tea spoon of oil in the cylinder give it a few secs and retest the comp. If the ring is bad the oil will work as a temp seal and comp numbers will go back up.
Or since you have the head off already just go ahead and replace the rings, you already have it half way torn down.
