05 5.3 idle and oil pressure

My 05 5.3 has 102k miles. It was my grandfather’s and was kept well care of. It runs fine think but at red lights I notice a random rough idle for a split second and notice the rpm drop just a hair and it’s back to normal. I know I have been told to check the EAF, MAS, and try cleaning the throttle body butterfly valve. Any thoughts?
Also, my oil pressure seems to run pretty normal at 40 when at a cruising speed but can pick up to about 65 max when gaining rapid speed on freeway or drop to 25 at a red light. Is this normal?
I am new to maintaining my own vehicle and trying to learn what is normal and what to watch out for. Any advice helps. Thanks.
