Usually, each application has menu which can be shown by clicking the title bar. But in case of Media Player, I cannot see it, too. Maybe, it's because I have no plugins?
I would say that the most important information lacking (should be a sticky on the device) is that ovi suite backup is completely and utterly worthless and doesn't backup anything except contacts and calendar (even if it does pretend to backup plenty of other things).
Warning people to use N900s built in backup instead (and thus making the memory card mandatory) is something that is far more important than quick start guide.
