I don't see how the help file isn't good enough, honestly, it seems pretty detailed to me: http://help.adobe.com/en_US/PremierePro/4.0/
As for the issue #2...yeah, I have to admit that is a lame thing of CS4. I thought it was a bug or something due to the fact that I have the beta version, but apparently, it's still there in the final version, from what you say. A shame, I guess.
But I like a lot the new things of it, so I guess I can let this slide, personally. >_>
