Level sounds fine. Trust the dipstick. Level should be checked when the engine is at operating temp and after idling for 30 seconds or so. The hotter the engine/oil, the higher the level. It'll be lower when driving when more oil is circulating and lower when you're at idle.
Pressure - yes I would expect some more variation than you're seeing. For a 3.2 when warm and idling, I think around 1 at 1,000 rpm is normal/fine. From memory, mine would idle around 1 and rise to around 4 I think. 3 seems ok to me but it should be moving - check the sender
