The low indicated oil pressure at idle...especially the low rpm idle you mentioned is typical. After you clean the idle speed control, locate and clean the single wire connection at the oil pressure sensor. It's just below the oil filter. Frequenly cleaning the connection improves the accuracy of the indicated pressure at idle, since at idle the signal is weakest. If your oil is thinned by fuel dilution or has a low viscosity rating, this will also affect what you see on the gauge...especially at idle.
In some cases you may need to change the oil pressure sensor.
