now can i do just this one cylinder or does that make any sense seeing as its apart and all...??

It has to come apart. Your only long shot chance is adjusting the vavles and trying again, but with those compresion numbers, there is a problem in the head. I doubt it is a valve adjustment problem.

At this point, there is nothing you can do from the outside to fix this problem. The head has to come off before you really know any more.
