Idle speed/oil pressure

I noticed something weird about my 300SD. When the engine is cold, it idles around 600rpm. After you drive it for a minute or two, it idles around 7-800rpm. Is this normal behavior for these diesels?

Additionally, when the motor is cold, idle oil pressure is always on "3". After it warms up, it drops down to 2-2.5. My 77 300D does about the same, but drops slightly lower when warmed up. What is the normal behavior for oil pressure?
