Each car shift differently; The same with drivers ...
I just read the 3000rpm comment; it's not really a rule but it does- as someone else noted- help a beginner with a reference point where to shift.
Generally, it's a lot easier to shift smoother @ higher rpm than lower. Once i'm in gear I like to maintain it @ 2000 rpm. I have friends where they stay in 3rd at 40- 45mph @ 3k+ rpm; Where I would drop it to 4th @ slightly above 2000 rpm
Basically I shift around 4k+ rpm and stay in gear @ 2k rpm. Downshift for anything lower.
And to smooth the transition, I personally hold the clutch for a half a second before fully engaged.
