While emissions tests suck their main purpose is to identify gross polluters and you are definitely there. You have both a mixture problem at idle and one or more ignition, injection, or valve loose head problem. If all is well with working catalyst those readings should be near 0. Without or before the cat O2 should be below 1.2% and HC. Well below 200.
