Your oil pump is fine. Those pressure readings seem normal to me. As for the oil leak you could start by just pulling one intake bolt at a time and apply some aviation gasket sealer to the threads than re-install. I have had coolant puddle up on the intake before from the manifold bolts leaking, but never oil although it could be possible. I would start by applying sealant to the intake bolts first though as thats cheap and easy to do. Good luck!!!!!
