Since this is a new car to you, when you change the filter look at the area where the filter screws on. There will be a pipe nipple hanging down that the filter screws on to. Just to one side should be a small circular area which holds the bypass valve. The bypass valve is a small spring loaded disk that lets oil bypass the filter should the filter become clogged. One trick that some guys do is to plug the bypass hole so it will not bypass the filter and allow dirty oil into the motor.
Your oil pressures are fine, but if your bypass valve has been disabled, don't get too radical with the motor until it warms up. Cold oil can raise your oil pressure to the point that the filter will rupture if you rap the motor up cold. If the bypass is in tact, I wouldn't worry about a thing.
