The cover image stored in iTunes is the one shown by the iPhone when you browse albums with Cover Flow. If you don't have a cover image for all your albums, you can download them from iTunes directly, but this requires an iTunes Store account, which in turns require you to leave them your credit card (even if you don't intend to make a purchase).

iArtWork is a great alternative that integrates perfectly with iTunes, is 100% freeware and is super simple to use. Just run it, and it will automatically download the covers for all albums in iTunes that don't have one already, and update the information directly into iTunes.

There is no menu item to activate it. When in the iPod application you're on the screen that lists all albums, rotate the iPhone horizontally so that you see it in landscape mode. This automatically enters the Cover Flow mode. Now simply browse the album covers by moving your finger over them.

No you can't, only the MP4 and H.264 video formats are directly supported. Support for other video formats may come later by third party developers though. If you have WMV and other DivX movies, you can convert them to a video format supported by Apple. Take a look at the open-source HandBrake tool for a free solution specific to iPhone video conversions.
