Looks great. A few comments on your notes:
2008 may have the USB/iPod connectivity as an option. If you have the USB and headphone jack in the console, you have it. You need a black Y cable for connectivity. If iDrive it should show Aux devices and your iPod. If not, it's still selectable thru the radio and should show playlists and songlists for selecting, skipping them.
For rain sensing wipers, press the end button once for a quick wipe and to activate. Use the wheel just next to the end to adjust sensitivity. I always do full up.
